The anatomical arrangement of the atrioventricular node has been likened to a riddle wrapped up in an enigma. There are several reasons for this alleged mystery, not least the marked variability in structure between different species. Lack of detailed knowledge of the location of the node relative to the atrial and ventricular septal structures has also contributed to previous misunderstandings. Recent studies comparing the findings of gross dissection with virtual dissection of living datasets, combined with access to a large number of serially sectioned human and animal hearts, have served to provide the evidence to solve the riddle. We summarise these findings in this review. We explain how the node is located within the atrial walls of the inferior pyramidal space. It becomes the non-branching component of the atrioventricular conduction axis as the axis extends through the plane of atrioventricular insulation to enter the infero-septal recess of the left ventricular outflow tract. The node itself is formed by contributions from the tricuspid and mitral vestibules, with extensive additional inputs from the base of the atrial septum. We show how knowledge of development enhances the appreciation of the arrangements and offers an explanation as to why, on occasion, there can be persisting nodoventricular connections. We discuss the findings relative to the circuits producing atrioventricular re-entry tachycardia. We conclude by emphasising the significance of the variation of the anatomical arrangements within different mammalian species. Full article

With its high spatial resolution and tissue contrast, cardiac magnetic resonance (CMR) is an extremely flexible imaging technique that enables a thorough morphological and functional evaluation of the heart and vascular system. From diagnosis to treatment planning and risk assessment, CMR is being utilized more and more in the evaluation of patients with heart failure (HF). CMR offers a variety of techniques for characterizing myocardial tissue, aiding in identifying the cause of HF, as well as whole-heart cine imaging for precise measurement of biventricular dimensions and function. The aim of this review is to the describe the role of CMR in chronic heart failure, in particular for diagnostic workups, differential diagnosis, and information on how CMR influences treatment planning choices.

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiomyopathy, caused by either sarcomere protein or other gene mutations. It is a complex and highly heterogeneous disorder, with phenotypes ranging from asymptomatic to severe disease, characterized by asymmetric left ventricular (LV) hypertrophy unexplained by loading conditions, which is also associated with myocardial fiber disarray, and preserved or increased ejection fraction without LV dilation. Comprehensive personal and family history, physical examination, and ECG testing raise suspicion of HCM, and echocardiogram represents the first-line imaging modality for confirming a diagnosis. Moreover, contrast-enhanced cardiac magnetic resonance (CMR) imaging has increasingly emerged as a fundamental diagnostic and prognostic tool in HCM management. This article reviews the role of CMR in HCM identification and differentiation from phenotypic mimics, characterization of HCM phenotypes, monitoring of disease progression, evaluation of pre- and post-septal reduction treatments, and selection of candidates for implantable cardioverter-defibrillator. By providing information on cardiac morphology and function and tissue characterization, CMR is particularly helpful in the quantification of myocardial wall thickness, the detection of hypertrophy in areas blind to echocardiogram, subtle morphologic features in the absence of LV hypertrophy, myocardial fibrosis, and apical aneurysm, the evaluation of LV outflow tract obstruction, and the assessment of LV function in end-stage dilated HCM.

Aortic valve disease accounts for approximately 5% of all congenital heart defects in children. Choosing the optimal valve replacement in this population is challenging, as it must ensure durability, accommodate growth, and minimize the need for long-term anticoagulation. Biological valves do not require anticoagulation but lack durability and growth potential, leading to frequent reoperations. Mechanical valves offer longevity but necessitate lifelong anticoagulation and do not grow with the child. Among the available surgical options, the Ross procedure has emerged as a preferred approach due to its favorable hemodynamic performance, growth potential, and freedom from anticoagulation. First described in 1967, this technique involves replacing the diseased aortic valve with a pulmonary autograft and reconstructing the right ventricular outflow tract using a human or non-human valve substitute. Despite its advantages, the procedure is technically demanding, has a considerable learning curve, and transforms a single-valve pathology into a bivalvular condition. This narrative review provides an updated perspective on the Ross procedure in children, focusing on long-term survival, reoperation rates, and the role of percutaneous valve replacement in delaying surgical reintervention. By synthesizing the latest evidence, we aim to clarify the current standing of the Ross procedure as a durable and effective solution for pediatric aortic valve disease. Full article

Background: Gastrointestinal bleeding in patients with atrial fibrillation is an indication for left appendage occlusion. All endovascular devices mandate antithrombotic therapies: rebleeding risk remains an issue. To date, there are no reports on gastrointestinal rebleeding and stroke prevention by left appendage occlusion without any antithrombotic therapy in this category of patients. Methods: A total of 129 patients (male 85, mean age 76.6 ± 7.1, CHA₂DS₂Vasc 3.8 ± 1.5, HASBLED 3.3 ± 1.0; upper GI bleeding 10%, lower GI bleeding 86%, obscure occult 4.6%, on NOACS full dose 77.5%, NOACs reduced dose 13.1%, on anti-vitamin K 9.3%) with atrial fibrillation and history of repetitive gastrointestinal bleeding from ten centers underwent standalone thoracoscopic epicardial appendage closure without antithrombotic therapy for the entire follow up. Results: The observed bleeding rate was 0.91 events per year, equivalent to a relative risk of RR = 0.17 (p = 0.02) and a relative risk reduction (RRR) of 83%. The observed relative risk of stroke was 0.91 events per year, with a relative risk of RR = 0.19 (p = 0.03) and a relative risk reduction (RRR) of 81%. Conclusion: Standalone epicardial appendage occlusion without antithrombotic therapy in patients with repetitive gastrointestinal bleeding is safe and promising when rebleeding and stroke risk reduction need to be optimized.

Bicuspid aortic valve (BAV) and thoracic aortic aneurysms and dissections (TAAD) are recognized in syndromic connective tissue diseases (CTD), but most cases occur sporadically. The extent to which non-syndromic BAV or TAAD predisposes to additional arteriopathies, particularly in younger individuals, remains unclear. We retrospectively analyzed 1438 patients (mean age = 48.0, 67.7% female), excluding those with CTDs. Participants were ≤60 years old and categorized by the presence of BAV and/or TAAD. We examined co-existing arterial pathologies, including fibromuscular dysplasia, spontaneous coronary artery dissection, abdominal aortic aneurysms (AAA), mesenteric, peripheral extremity, and carotid/cerebral arteriopathies. Overall, 44.6% had either BAV or TAAD, and 27.2% had multiple arteriopathies. While vascular diseases were frequently noted, odds ratios demonstrated no significantly increased risk of extra-aortic arteriopathies in the BAV or TAAD cohorts. AAA exhibited a non-significant trend toward higher prevalence in TAAD patients. These findings support current guidelines recommending targeted imaging (transthoracic echocardiography of the aortic root and ascending aorta) over comprehensive “head-to-pelvis” screening for non-syndromic BAV or TAAD patients without additional risk factors. Ongoing genetic analyses may elucidate whether particular variants predispose to multi-site aneurysms or dissections. Consequently, targeted surveillance remains appropriate, with broader imaging reserved for patients with genetic or clinical indicators of higher risk. Full article

Background: While left-bundle-branch-block-related contraction patterns as well as echocardiography-derived strain are variably associated with the volumetric response to cardiac resynchronization therapy (CRT), the role of CMR-derived strain parameters is unexplored. Methods: A total of 50 patients receiving CRT implantation were retrospectively analyzed, all of whom had undergone CMR imaging within one year before, and echocardiography within 6 months before and 6–12 months after CRT implantation. We assessed CMR-derived morphological and functional parameters with regard to the echocardiographic response, defined as a reduction in the left ventricular end-systolic volume of ≥15%. Results: Among the standard CMR parameters, the indexed right ventricular volumes in end-diastole (RVEDVi) (74.5 ± 19.5 vs. 94.8 ± 30.2 mL/m², p = 0.006) and end-systole (RVESVi) (43.2 ± 13.3 vs. 61.6 ± 28.8 mL/m², p = 0.003), as well as the left atrial (LA) area (24.8 ± 3.5 vs. 30.4 ± 9.5 cm², p = 0.020), differed significantly between CRT responders and non-responders. In strain analysis, CRT responders showed a significantly better LA global longitudinal strain (GLS) (25.1 ± 10.4 vs. 15.3 ± 10.5, p = 0.002), LA global circumferential strain (GCS) (27.9 ± 14.7 vs. 17.1 ± 13.1%, p = 0.012), RV GLS (−25.0 ± 6.5 vs. −18.9 ± 7.6%, p = 0.004) and RV free wall strain (−31.1 ± 7.9 vs. −24.9 ± 9.5, p = 0.017). Conclusions: CMR-derived peak septal circumferential strain and RVEDVi correlated with the echocardiographic volumetric response to CRT at 6–12 months. Full article

Background: Acute aortic valve infective endocarditis (IE) presents a critical surgical timing dilemma. This study investigates whether early surgical intervention (within seven days of targeted antibiotic therapy initiation) affects mortality and clinical outcomes compared to delayed/conventional surgery. Methods: A retrospective, multicenter analysis of 204 patients with aortic IE was conducted, excluding emergency cases requiring immediate intervention. Patients were stratified into EARLY (≤7 days) and LATE (>7 days) surgical groups. Primary endpoints included in-hospital mortality and major adverse events, while secondary endpoints assessed long-term survival, recurrence, and reintervention rates. Results: No significant differences in in-hospital mortality were observed between groups (16% in both). The LATE group exhibited a trend toward increased permanent pacemaker implantation (16% vs. 8.2%; p = 0.100) and a higher incidence of postoperative atrial fibrillation (36% vs. 24%, p = 0.048). Infective endocarditis recurrence and long-term survival did not significantly differ between groups. Predictors of one-year mortality included chronic kidney disease, annular abscess, extracorporeal membrane oxygenation (ECMO) use, and prolonged mechanical ventilation. Conclusions: These findings suggest that early surgery, following a short course of antibiotics, does not compromise outcomes nor increase recurrence risk, challenging the conventional preference for delayed intervention in non-emergency IE cases.

Neuroprotective strategies in coronary artery interventions are essential due to the rising number of high-risk patients undergoing procedures like coronary artery bypass grafting (CABG), totally endoscopic coronary artery bypass (TECAB), and hybrid revascularization. In this review article, we summarize the neurological complications associated with coronary artery disease intervention and the risk mitigation strategies. CABG carries significant risks, including ischemic stroke, encephalopathy, seizures, and peripheral nerve injuries. Risk factors include advanced age, hypertension, diabetes, and atherosclerosis. Off-pump CABG minimizes stroke risk by avoiding aortic manipulation and CPB. TECAB and hybrid revascularization have fewer reported neurological complications but still pose risks of stroke and cranial nerve injuries. Pharmacological neuroprotection includes agents such as barbiturates, volatile anesthetics, lidocaine, NMDA receptor antagonists, magnesium, nimodipine, corticosteroids, and aprotinin. Deep hypothermic circulatory arrest (DHCA) is reserved for complex aortic cases requiring a bloodless surgical field. Intraoperative strategies involve cerebral perfusion monitoring, embolic protection devices, and therapeutic hypothermia. Preoperative optimization targets risk factors, arrhythmia prevention, and antiplatelet therapy management. Postoperatively, timely antiplatelet administration, glucose control, hemodynamic stabilization, and cognitive monitoring are critical. Comprehensive neuroprotective approaches, spanning pre- to postoperative phases, aim to reduce neurological complications and enhance outcomes in coronary interventions. Full article

Background and aims: His bundle pacing (HBP) is considered the most physiological form of cardiac pacing. Although feasibility studies have included older patients, specific data for HBP in this population are scarce. This study aimed to evaluate gender differences in HBP long-term performance in elderly patients with atrioventricular (AV) block. Methods: This retrospective study included 73 patients aged over 65 years with successful HBP and at least 2 years of follow-up. The patients’ baseline and follow-up clinical and procedural characteristics were recorded. Results: The mean age of the cohort was 72.8 ± 6.3 years, with 43 males and 30 females. The paced QRS complex was significantly narrower than the baseline value for both genders. Females had a narrower-paced QRS complex without differences in detection, type of His bundle capture, impedance, or fluoroscopy time. The pacing threshold increased progressively, reaching statistical significance compared to the baseline values at the two-year follow-up. The pacing threshold increased by more than 1 V over the follow-up period in twenty-four patients (32.9%) and by more than 2 V in six patients (8.2%), with no significant difference between genders. The pacing threshold increase occurred within the first year for most patients, without gender differences. Multivariate Cox regression analysis demonstrated that the paced QRS duration, left ventricular ejection fraction, and ischemic cardiomyopathy were significantly associated with the pacing threshold increase over time. Conclusion: In elderly patients with AV block, HBP remains a feasible pacing method, without significant gender differences, over a long-term follow-up period. Pacing threshold increases are expected in up to one-third of the patients, requiring regular follow-ups to adjust the programmed parameters and optimize battery longevity. Full article

Surgical Aortic Valve Replacement (SAVR) is still one of the pillars of cardiac surgery practice, and its role is evolving into a more complex operation. The competition with structural valve therapies and the urgent demand for less invasive solutions have unleashed surgeons’ creativity in adapting to these new challenges. All the possible ways to surgically replace the aortic valve are analyzed in this review. Surgical techniques, advantages and disadvantages, and key differences are listed, helping surgeons navigate the available options. Sternotomy SAVR is the benchmark, but that is becoming obsolete and, in some cases, no longer performed for teaching purposes. Mini sternotomy is the easiest way to achieve minimal invasiveness in all anatomic situations, while right anterior thoracotomy is an elegant solution mastered by fewer surgeons. Endoscopic and robotic-assisted techniques are shaping the future of SAVR, yet they still lack wide adoption. The choice of approach is mainly dictated by the anatomic features of the patient and the surgeon’s skills. A flow diagram to overcome the learning curve and advance toward more complex surgery is provided here. Mastering as many techniques as possible is paramount when offering a patient-tailored approach and performing a safe and less invasive operation. Full article

AIM: Higher exercise blood pressure in adults correlates with many cardiometabolic markers. The aim of this study was to investigate the main determinants of longitudinal variations in exercise blood pressure in young athletes. METHODS: A longitudinal retrospective study was conducted on adolescent athletes who underwent at least two sport-related pre-participation screening visits, including exercise testing with a standardized incremental ramp protocol on treadmill. Blood pressure was assessed at rest (SBP_rest), at the 3rd minute of exercise (SBP_3min), and at peak exercise (SBP_peak). Predictors of blood pressure response (i.e., respective changes vs. baseline (Δ)) were determined by multivariate regression models after adjustment for age, sex, follow-up duration, related baseline SBP values, characteristics of sport, and ΔBMI. RESULTS: A total of 351 young athletes (mean age at baseline 13 ± 2 years, 54% boys, average follow-up duration 3.4 ± 2.2 years) were enrolled. BMI increased by 1.5 ± 1.8 kg/m² (p < 0.001) during follow-up. At baseline, mean SBP_rest was 103 ± 14 mmHg, mean SBP_3min 124 ± 18 mmHg, and mean SBPpeak 154 ± 23 mmHg. A significant between-visit increase in SBP_rest (ΔSBP_rest 7.0 ± 17.4 mmHg; p < 0.001), ΔSBP_3min (4.8 ± 11 mmHg, p < 0.001), and ΔSBP_peak (11.7 ± 24 mmHg, p < 0.001) was observed. ΔSBP_3min was significantly predicted by male sex (p < 0.01), baseline BMI (p < 0.01), ΔBMI (p < 0.01), and number of practiced sports (p < 0.05), whereas ΔSBP_peak was positively predicted by male gender (p < 0.01), baseline BMI (p < 0.05), and ΔBMI (p < 0.01) and negatively by baseline resting heart rate (p < 0.01). In a logistic regression model, ΔBMI was the only independent determinant of passing from a lower to an upper quartile of SBP_3min (p < 0.001), while ΔBMI and male sex were independent determinants of moving to a higher quartile of SBP_peak (p < 0.001). CONCLUSIONS: Increase in BMI during development and male sex are independent determinants of the increase in exercise blood pressure, both at light and maximal intensity, in a population of adolescent athletes.

Subclinical leaflet thrombosis is an imaging phenomenon observed after transcatheter aortic valve implantation (TAVI) and characterized by hypoattenuating leaflet thickening (HALT) on computed tomography angiography. The clinical implications and underlying causes remain uncertain. Hypercoagulability, a component of Virchow’s triad, may contribute to thrombus formation on bioprosthetic leaflets, but data on hypercoagulable disorders in TAVI patients and their impact on HALT are limited. The PROSTHESIS study (Prothrombotic States in Transcatheter Heart Valve Subclinical Leaflet Thrombosis) is a single-center observational cohort study aiming to include 130 TAVI patients. This pilot study aimed to (i) assess the effect of hypercoagulable disorders on HALT prevalence and (ii) evaluate their impact on the natural history of HALT. Patients were screened for common hypercoagulable disorders using genetic and functional assays and underwent multimodal imaging one year after TAVI to detect HALT. In patients with HALT, post-implant imaging was repeated after three months to assess its progression. Early results comparing 52 TAVI patients with 52 matched controls undergoing coronary angiography showed similar thrombophilia prevalence between the groups (16% vs. 12%, p = 0.565). HALT occurred in 15% of TAVI patients, more extensively in those with thrombophilia (712 mm³ vs. 135 mm³, p = 0.036). However, thrombophilia was not an independent predictor of HALT. One-year follow-up CTA revealed spontaneous HALT resolution in 63%, stability in 25%, and progression in 12%. This study aims to provide insights into HALT and its mechanisms, which may help prevent complications and improve bioprosthesis durability. Full article

An artificial intelligence (AI) analysis of electronic medical records (EMRs) was performed to analyze the differences between patients with carotid stenosis who developed symptomatic disease and those who remained asymptomatic. The EMRs of 872 patients who underwent a carotid endarterectomy between 2009 and 2022 were analyzed with AI. This included 408 patients who had carotid intervention for symptomatic carotid disease and 464 patients for asymptomatic, >70% stenosis. By analyzing the EMRs, the Support Vector Machine achieved the highest sensitivity at 0.626 for predicting which of these patients would go on to develop a stroke or TIA. Random Forest had the highest specificity at 0.906. The risk for stroke in patients with carotid stenosis was a balance between optimum medical treatment and the underlying disease processes. Risk factors for developing symptomatic carotid disease included elevated glucose, chronic kidney disease, hyperlipidemia, and current or recent smoking, while protective factors included cardiovascular agents, antihypertensives, and beta blockers. An AI review of EMRs can help determine which patients with carotid stenosis are more likely to develop a stroke to assist with decision making as to whether to proceed with intervention or to demonstrate and encourage reduced stroke risk with risk factor modification.

Vulnerable coronary atherosclerotic plaque involves a dynamic pathophysiologic process within and surrounding an atheromatous plaque in coronary artery intima. The process drastically increases the risk of plaque rupture and is clinically responsible for most cases of acute coronary syndromes, myocardial infarctions, and sudden cardiac deaths. Early detection of vulnerable plaque is crucial for clinicians to implement appropriate risk-mitigation treatment strategies, offer timely interventions, and prevent potentially life-threatening events. There is an imperative clinical need to develop practical diagnostic pathways that utilize non-invasive means to risk-stratify symptomatic patients. Since the early 1990s, the identification of vulnerable plaque in clinical practice has primarily relied on invasive imaging techniques. In the last two decades, CT coronary angiogram (CTCA) has rapidly evolved into the prevalent non-invasive diagnostic modality for assessing coronary anatomy. There are now validated plaque appearances on CTCA correlating with plaque vulnerability. It is worth noting that in clinical practice, most CTCA reports omit mention of vulnerable plaque details because spatial resolution (0.3–0.5 mm) is often insufficient to reliably detect some crucial features of vulnerable plaques, such as thin fibrous caps. Additionally, accurately identifying vulnerable plaque features requires substantial expertise and time, which many cardiologists or radiologists may lack in routine reporting. Cardiac magnetic resonance imaging (cMRI) is also non-invasive and allows simultaneous anatomic and functional assessment of coronary plaques. Despite several decades of research and development, routine clinical application of cMRI in coronary plaque imaging remains hampered by complex imaging protocols, inconsistent image quality, and cost. Molecular imaging with radiotracers, specifically positron emission tomography (PET) with sodium fluoride (Na¹⁸F PET), have demonstrated significant potential as a sensitive and specific imaging procedure for diagnosing vulnerable coronary artery plaque. The study protocol is robust and brief, requiring minimal patient preparation. Compared to CTCA and cMRI, the diagnostic accuracy of this test is less dependent on the experience and expertise of the readers. Furthermore, validated automated quantitative algorithms complement the visual interpretation of the study, enhancing confidence in the diagnosis. This combination of factors makes Na¹⁸F PET a promising tool in cardiology for identifying high-risk coronary plaques. Full article

Mitochondria play a crucial role in multiple cellular processes such as energy metabolism, generation of reactive oxygen species, excitation–contraction coupling, cell survival and death. Dysfunction of mitochondria contributes to the development of cancer; neuromuscular, cardiovascular/congenital heart disease; and metabolic diseases, including diabetes. Mitochondrial dysfunction can result in excessive reactive oxygen species, a decrease in energy production, mitophagy and apoptosis. All these processes are known to be dysregulated in cardiovascular diseases. The focus of this review is to summarize our current knowledge of mitochondrial dysfunction, including mitophagy and apoptosis, in pediatric congenital heart disease due to maternal diabetes or due to structural cardiac defects, with a focus on single-ventricle congenital heart disease. We also discuss recent mitochondria-targeted therapies for cardiovascular diseases. Full article

Impaired glucose tolerance (IGT), a prediabetic state, is a known risk factor for coronary artery disease (CAD). Low-attenuation plaque (LAP) lesions are associated with a high risk of coronary events. We aimed to evaluate high-risk plaque characteristics in LAP lesions between patients with IGT and normal glucose tolerance (NGT) in patients suspected for stable CAD. Coronary computed tomography angiography (CCTA) identified LAP lesions and assessed plaque volumes, burdens, and high-risk plaque features. Glycemic tolerance was stratified using oral glucose tolerance tests. Among 148 patients, 202 LAP lesions were identified, with 93 patients classified as NGT and 55 as IGT. Patients with IGT had a significantly higher prevalence of LAP lesions compared with NGT (p = 0.007). LAP volume was higher in IGT (16.46 ± 12.52 mm³) compared with NGT (12.66 ± 9.72 mm³, p = 0.01), but this association did not persist in multivariate analysis. The LAP burden was greater in IGT (10.79 ± 6.84%) than NGT (8.62 ± 5.93%, p = 0.02), and the napkin-ring sign was more frequent in IGT (12%) versus NGT (5%, p = 0.02); these associations remained significant in multivariate analysis. Patients with IGT had a higher LAP burden and higher frequency of napkin-ring signs. These findings may help explain the common occurrence of prediabetes in patients with acute myocardial infarction.

Coronary artery disease (CAD) is usually associated with the elderly, but an increase in its incidence has been recently reported among young people, including very young women. The aim of this study is to assess the associations between different clinical variables and the risk of early CAD and occurrence of major adverse cardiovascular events (MACEs) during follow-up. Our cohort consists of women ≤40 years referred for coronary angiography due to suspicion of CAD; a nested case–control study was conducted among these patients. In total, 19,321 coronary angiographies were performed between 2006 and 2015, of which 2.6% were in patients ≤40 years old; 52 women were finally included. Family history of CAD was strongly associated with the early onset of the disease [OR 5.94, 95%CI (1.13–31.15); p = 0.035] in young women. The incidence of MACE was also associated with depression [HR 8.20 95%CI (1.03–65.17); p = 0.047] and Castelli Index [HR 11.49, 95%CI (1.40–94.51); p = 0.023]. Primary prevention focused on genetic analysis for high-risk women with a family history of CAD and secondary prevention, targeting a better cholesterol management and mental health assistance must be considered.

Understanding hormonal and molecular changes during the transition from preterm to near-term gestation is essential for investigating how pregnancy complications impact fetal heart development and contribute to long-term cardiovascular risks for offspring. This study examines these cardiac changes in fetal sheep, focusing on the changes between 116 days (preterm) and 140 days (near term) of gestation (dG, term = 150) using Western blotting, LC-MS/MS, and histological techniques. We observed a strong correlation between cortisol and T₃ (Triiodothyronine) in heart tissue in near-term fetuses, highlighting the role of glucocorticoid signalling in fetal heart maturation. Protein expression patterns in the heart revealed a decrease in multiple glucocorticoid receptor isoforms (GRα-A, GR-P, GR-A, GRα-D2, and GRα-D3), alongside a decrease in IGF-1R (a marker of cardiac proliferative capacity) and p-FOXO1(Thr24) but an increase in PCNA (a marker of DNA replication), indicating a shift towards cardiomyocyte maturation from preterm to near term. The increased expression of proteins regulating mitochondrial biogenesis and OXPHOS complex 4 reflects the known transition from glycolysis to oxidative phosphorylation, essential for meeting the energy demands of the postnatal heart. We also found altered glucose transporter expression, with increased pIRS-1(ser789) and GLUT-4 but decreased GLUT-1 expression, suggesting improved insulin responsiveness as the heart approaches term. Notably, the reduced protein abundance of SIRT-1 and SERCA2, along with increased phosphorylation of cardiac Troponin I(Ser23/24), indicates adaptations for more energy-efficient contraction in the near-term heart. In conclusion, these findings show the complex interplay of hormonal, metabolic, and growth changes that regulate fetal heart development, providing new insights into heart development that are crucial for understanding pathological conditions at birth and throughout life.

Background: Xanthine oxidase inhibitors (XOIs) may help prevent stroke. However, heterogeneity can be found in the conclusions of different studies. The relevant evidence was summarized in this systematic review and meta-analysis to further clarify the role of XOIs in the prevention and treatment of stroke, with a focus on evaluating the effects of XOIs in primary and secondary prevention of stroke, acute stroke treatment, and reduction of post-stroke complications. Methods: Randomized controlled trials (RCTs) or cohort studies on the effect of XOIs in the prevention and treatment of stroke were searched in PubMed, EMBASE, and Cochrane Library from inception to 3 March 2024, along with hand searching. The analyses were carried out using Review Manager 5.4. Results: The analysis included 14 studies (115,579 patients). While XOIs did not significantly reduce the risk of stroke (RR: 0.89; 95% CI: 0.59–1.34), they improved post-stroke functional outcomes, with a reduction in the modified Rankin scale scores (mean difference: −0.6; 95% CI: −0.8 to −0.4), decreased intercellular adhesion molecule-1 levels (mean difference: −15.2 ng/mL; 95% CI: −22.3 to −8.1), improved augmentation index (AIx) by 4.2% (95% CI: 2.5–5.9%), reduced central blood pressure (mean reduction: 4.8 mmHg; 95% CI: 2.6–6.9), and delayed carotid intima-media thickness progression (mean difference: −0.05 mm/year; 95% CI: −0.08 to −0.02).

Myocardial infarction (MI) is a significant cardiovascular event caused by the decrease in or complete cessation of blood flow to a portion of the myocardium. It can arise from a variety of etiological factors, including pharmacological triggers. This review aims to explore the diverse drugs and substances that might lead to drug-induced myocardial infarction, focusing on their mechanisms of action and the pathophysiological processes involved. Various established and emerging pharmacological agents that could elevate the risk of myocardial infarction, such as nonsteroidal anti-inflammatory drugs, hormonal therapies, anticoagulants, and antipsychotic medications, are discussed. The role of drug-induced endothelial dysfunction, coronary artery spasm, and thrombosis are presented in order to highlight the underlying mechanisms. This review emphasizes the need for increased awareness among healthcare professionals to mitigate the risks associated with different pharmacological therapies to improve patient outcomes.

Background. Major aortopulmonary collateral arteries (MAPCAs) are rare remnants of pulmonary circulation embryological development usually associated with complex congenital anomalies of the right ventricular outflow tract and pulmonary arteries. Effective management requires surgical unifocalization of MAPCAs and native pulmonary arteries (NPAs). Traditional imaging may lack the spatial clarity needed for precise surgical planning. Aim. This study evaluated the feasibility of integrating three-dimensional (3D) printing and virtual reality (VR) into preoperative planning to improve surgical precision, team communication, and parental understanding. In a prospective cohort study, nine infants undergoing MAPCA unifocalization were included. Four patients underwent conventional imaging-based planning (control), while five were additionally assessed using VR and 3D-printed models (intervention). The outcomes measured included operative times, team confidence, collaboration, and parental satisfaction. Statistical analysis was performed using standard tests. Results. The intervention group had shorter operative and cardiopulmonary bypass times compared to the control group. Intraoperative complications were absent in the VR/3D group but occurred in the control group. Medical staff in the VR/3D group reported significantly improved understanding of anatomy, surgical preparedness, and team collaboration (p < 0.05). Parents also expressed higher satisfaction, with better comprehension of their child’s anatomy and surgical plan. Conclusions. VR and 3D printing enhanced preoperative planning, surgical precision, and communication, proving valuable for complex congenital heart surgery. These technologies offer promising potential to improve clinical outcomes and patient–family experiences, meriting further investigation in larger studies. Full article

Objective: Cardiac computed tomography (CT) helps screen coronary artery stenosis in cases with dilated cardiomyopathy (DCM). Extracellular volume fraction (ECV) analysis has recently been eligible for CT. Method: We evaluated the impact of ECV on the CT to predict the prognosis in DCM patients with heart failure with reduced ejection fraction (HFrEF). Patients or Materials: We analyzed 101 consecutive DCM cases with HFrEF who underwent cardiac CT. All the patients had a lower left ventricular (LV) ejection fraction (LVEF) of less than 40%. We evaluated the effect of ECV to predict the patients’ prognosis. Cardiovascular death, hospitalization due to heart failure, and fatal arrhythmic events were included in the major adverse cardiac events (MACE). Results: MACE occurred in 27 cases (27%). The patients with MACE (27 cases) had an increased ECV on the LVM on the CT (37.2 ± 6.7 vs. 32.2 ± 3.6%, p = 0.0008) compared to the others (74 cases). Based on the receiver operating characteristics curve analysis, the best cutoff value of the ECV on the LVM to predict the MACE was 32.3%. The patients with ECV ≥ 32.3% had significantly higher MACE based on the Kaplan–Meier analysis. The ECV on the LVM was a significant marker to predict MACE based on the univariate Cox proportional hazard model (hazard ratio of 8.00, 95% confidence interval 1.88–33.97, p = 0.0048). Conclusions: ECV by CT is helpful to predict MACE in cases with DCM and HFrEF. Full article

Hypertrophic cardiomyopathy (HCM) is a complex and heterogeneous cardiac disorder, often complicated by cardiogenic shock, a life-threatening condition marked by severe cardiac output failure. Managing cardiogenic shock in HCM patients presents unique challenges due to the distinct pathophysiology of the disease, which includes dynamic left ventricular outflow tract obstruction, diastolic dysfunction, and myocardial ischemia. This review discusses current and emerging therapeutic strategies tailored to address the complexities of HCM-associated cardiogenic shock and other diseases with similar pathophysiology that provoke left ventricular outflow tract obstruction. We explore the role of pharmacological interventions, including the use of vasopressors and inotropes, which are crucial in stabilizing hemodynamics but require careful selection to avoid exacerbating the outflow obstruction. Additionally, the review highlights advancements in mechanical circulatory support devices such as extracorporeal membrane oxygenation (ECMO) and left ventricular assist devices (LVADs), which have become vital in the acute management of cardiogenic shock. These devices provide temporary support and bridge patients to recovery, definitive therapy, or heart transplantation, which remains a critical option for those with end-stage disease. Furthermore, the review delves into the latest research and clinical trials that are refining these therapeutic approaches, ensuring they are optimized for HCM patients. The impact of these treatments on patient outcomes, including survival rates and quality of life, is also critically assessed. In conclusion, this review underscores the importance of a tailored therapeutic approach in managing cardiogenic shock in HCM patients, integrating pharmacological and mechanical support strategies to improve outcomes in this high-risk population.

Three-dimensional (3D) printing is an advanced technology for accurately understanding anatomy and supporting the successful surgical management of complex congenital heart disease (CHD). We aimed to evaluate whether our super-flexible 3D heart models could facilitate preoperative decision-making and surgical simulation for complex CHD. The super-flexible heart models were fabricated by stereolithography 3D printing of the internal and external contours of the heart from cardiac computed tomography (CT) data, followed by vacuum casting with a polyurethane material similar in elasticity to a child’s heart. Nineteen pediatric patients with complex CHD were enrolled (median age, 10 months). The primary endpoint was defined as the percentage of patients rated as “essential” on the surgeons’ postoperative 5-point Likert scale. The accuracy of the models was validated by a non-destructive method using industrial CT. The super-flexible heart models allowed detailed anatomical diagnosis and simulated surgery with incisions and sutures. Thirteen patients (68.4%) were classified as “essential” by the primary surgeons after surgery, with a 95% confidence interval of 43.4–87.4%, meeting the primary endpoint. The product error within 90% of the total external and internal surfaces was 0.54 ± 0.21 mm. The super-flexible 3D heart models are accurate, reliable, and useful tools to assist surgeons in decision-making and allow for preoperative simulation in CHD. Full article

Gender medicine has increasingly underscored the necessity of addressing sex-based differences in disease prevalence and management, particularly within cardiovascular conditions and drug intolerance. Women often present cardiovascular diseases distinctively from men, with a higher prevalence of non-obstructive coronary artery disease and varied ischemic manifestations, such as coronary microvascular dysfunction and epicardial or microvascular coronary spasm. This disparity is further exacerbated by elevated drug intolerance rates among women, influenced by hormonal, genetic, and psychosocial factors. The 2024 ESC guidelines for managing chronic coronary syndromes stress the need for personalized approaches to treat angina and ischemia with non-obstructive coronary artery disease (ANOCA/INOCA), recommending a combination of antianginal medications. Despite standard treatments, up to 40% of ANOCA/INOCA patients experience refractory angina, necessitating a multifaceted approach that often involves multiple antianginal drugs, which can increase the likelihood of drug intolerances. Future research should focus on including women in drug studies and addressing sex-specific differences, while healthcare providers must be equipped to manage gender-specific drug intolerances. Enhanced awareness, individualized treatment strategies, and gender-sensitive healthcare policies are crucial for improving outcomes and bridging the gender gap in cardiovascular medicine.

Coenzyme Q10 (CoQ10) has been suggested as an adjunct therapy for endocrine and metabolic disorders. The aim of this study was to synthesise the evidence for the effect of CoQ10 supplementation on lipid and/or glycaemic alterations, including total cholesterol (TC), LDL- and HDL-cholesterol (LDL-C and HDL-C), lipoprotein a, fasting blood glucose (FBG), haemoglobin A1c (HbA1c), fasting insulin and Homeostatic Model Assessment of Insulin Resistance. A systematic search was conducted in Medline, Scopus, Web of Science and the Cochrane Library from their inception to July 2024. Meta-analyses that evaluated the effect of CoQ10 on the lipid or glycaemic profiles were included. Results were expressed as mean difference (MD) or standardised mean difference (SMD). CoQ10 showed an effect on the glycaemic profile, especially on FBG (MD from −11.21 to −5.2 mg/dL, SMD from −2.04 to −0.17) and on HbA1c (MD from −1.83 to −0.12%, SMD of −0.30). CoQ10 may also have an effect on the lipid profile, such as TC, triglycerides, HDL-C and even LDL-C, although the inconsistency of the results was somewhat higher. Supplementation with CoQ10 may be beneficial, especially in populations with diabetes mellitus or other endocrine and metabolic disorders. It could also have some effect on lipid parameters, which, together with the above, may reduce cardiovascular morbidity and mortality, although this is something that needs further research.

Background: Postoperative cardiac rehabilitation (CR) programs are increasingly recommended by clinicians, but only a minority of patients who have undergone open heart surgery participate in such programs. Participation rates in postoperative CR, if anything, appear to be declining. This systematic review examines the effectiveness of post-operative CR and reveals possible participation barriers. Methods: A search of two scholarly databases for primary research papers published in the last decade examining the impact of post-operative CR was conducted and the resultant papers reviewed. Results: The 21 resulting studies revealed physiological functioning improvement and a reduction in mortality and readmission rates, while highlighting an enhancement in mental status. Some of the studies recognized the need for nutritional support and suggested that age, gender, access to CR centers, and socioeconomic variables impact participation in CR. Conclusions: Post-operative CR participation rates continue to decline despite increasing evidence of the value of the approach. Full article

There is an increasing understanding that some mitral valve pathologies have developmental origins. The time course of valvulogenesis varies by animal model; in cattle, the branched chordae tendineae architecture becomes fully developed at full term. The mechanism by which chordae tendineae bifurcate during fetal development remains unknown. The current study presents a detailed description of bovine chordae tendineae formation and bifurcation during fetal development. Analysis of Movat Pentachrome-stained histological sections of the developing mitral valve apparatus was accompanied by micro-CT imaging. TEM imaging of chordae branches and common trunks allowed the measurement of collagen fibril diameter distributions. We observed a proteoglycan-rich “transition zone” at the junction between the fetal mitral valve anterior leaflet and chordae tendineae with “perforations” lined by MMP1/2 and Ki-67 expressing endothelial cells. This region also contained clusters of proliferating endothelial cells within the bulk of the tissue. We hypothesize this zone marks a region where chordae tendineae bifurcate during fetal development. In particular, perforations created by localized MMP activity serve as a site for the initiation of a “split” of a single chordae attachment into two. This is supported by TEM results that suggest a similar population of collagen fibrils runs from the branches into a common trunk. A clear understanding of normal mitral valvulogenesis and its signaling mechanisms will be crucial in developing therapeutics and/or tissue-engineered valve replacements. Full article

Coronary artery disease (CAD) remains a leading cause of morbidity and mortality worldwide, accounting for over 9 million deaths annually. The prevalence of CAD continues to rise, driven by ageing and the increasing prevalence of risk factors such as hypertension, diabetes, and obesity. Current clinical guidelines emphasize the importance of functional tests in the diagnostic pathway, particularly for assessing the presence and severity of ischemia. While recommended tests are valuable, they may not fully capture the complex physiological responses to exercise or provide the necessary detail to tailor personalized treatment plans. Cardiopulmonary exercise testing (CPET) offers a comprehensive assessment of the cardiovascular, pulmonary, and muscular systems under stress, potentially addressing these gaps and providing a more precise understanding of CAD, particularly in settings where traditional diagnostics may be insufficient. By enabling more personalized and precise treatment strategies, CPET could play a central role in the future of CAD management. This narrative review examines the current evidence supporting the use of CPET in CAD diagnosis and management and explores the potential for integrating CPET into existing clinical guidelines, considering its diagnostic and prognostic capabilities, cost-effectiveness, and the challenges associated with its adoption.

Cardiovascular disease (CVD) is the leading cause of death in Asians. We aimed to examine the validity and reliability of self-reported (SR) CVD in 6762 Chinese, Malay, and Indian adults aged 40–80 years who attended the baseline (November 2004) and 6-year follow-up visit (2011–2017) of a population-based cohort study in Singapore. CVD was defined based on the presence of existing (prevalent) or new onset (incident) cases of acute myocardial infarction (AMI) or stroke. The validity of SR-CVD was assessed by comparing it against diagnosed CVD using sensitivity and specificity. The reliability of SR-CVD was evaluated by calculating the percentage of positive agreement between baseline and follow-up visits. The sensitivity and specificity of SR-CVD were 62.7% and 93.8% for prevalent SR-CVD and 50.9% and 98.5% for incident SR-CVD. The negative predictive value (NPV) was 98.1% for both prevalent and incident SR-CVD. The reliability of positive self-reports between the baseline and follow-up was substantial, at 85%. The excellent specificity and NPV of SR-CVD suggest that it could serve as a valuable tool for excluding AMI and stroke. However, its moderate sensitivity suggests that positive SR-CVD reports should prompt further clinical evaluation to prevent potential false positives. Full article

Thoracic and abdominal aortic aneurysms (TAAs and AAAs, respectively) share morphological features but have distinct clinical and hereditary characteristics. Studies using bulk RNA comparisons revealed distinct patterns of gene expression in human TAA and AAA tissues. However, given the summative nature of bulk RNA studies, these findings represent the totality of gene expression without regards to the differences in cellular composition. Single-cell RNA sequencing provides an opportunity to interrogate cell-type-specific transcriptomes. Single cell RNA sequencing datasets from mouse TAA (GSE153534) and AAA (GSE164678 and GSE152583) with respective controls were obtained from the Gene Expression Omnibus. Bioinformatic analysis was performed with the Seurat 4, clusterProfiler, and Connectome software packages (V1.0.1). Immunostaining was performed with standard protocols. Within normal and aneurysmal aortae, three unique populations of cells that express smooth muscle cell (SMC) markers were identified (SMC1, SMC2, and SMCmod). A greater proportion of TAA SMCs clustered as a unique population, SMCmod, relative to the AAA SMCs (38% vs. 10–12%). These cells exhibited transcriptional features distinct from other SMCs, which were characterized by Igfbp2 and Tnfrsf11b expression. Genes upregulated in TAA SMCs were enriched for the Reactome terms “extracellular matrix organization” and “insulin-like growth factor (IGF) transport and uptake by IGF binding proteins (IGFBPs)”, indicating a role for Igfbp2 in TAA pathogenesis. Regulon analysis revealed transcription factors enriched in TAAs and AAAs. Validating these mouse bioinformatic findings, immunostaining demonstrated that both IGFBP2 and TNFRSF11B proteins increased in human TAAs compared to AAAs. These results highlight the unique cellular composition and transcriptional signature of SMCs in TAAs and AAAs. Future studies are needed to reveal the pathogenetic pathways of IGFBP2 and TNFRSF11B.

Background and Purpose: Perivascular spaces (PVS) are usually enlarged in small vessel disease (SVD). However, the significance of PVS patterns in different locations is uncertain. Hence, we analyzed the distribution of PVS in patients with a recent small subcortical infarct (RSSI) and their correlation with clinical and imaging factors. Materials and Methods: In a cohort of 71 patients with an RSSI with complete clinical data, including the Pittsburgh Sleep Quality Index (PSQI), we segmented PVS in white matter (WM-PVS), basal ganglia (BG-PVS), and brainstems (BS-PVS) on 3T-MRI T2-weighted sequences, obtaining fractional volumes (%), and calculated the WM/BG-PVS ratio. We analyzed the Pearson’s correlation coefficients between PVS regional loads. We used normalized PVS measures to assess the associations with clinical and MRI-SVD features (white matter hyperintensities (WMHs), number of lacunes, and microbleeds) in univariable and multivariable linear regressions adjusted for age, sex, and hypertension. Results: In our cohort (mean age 70 years; 27% female), the Pearson’s correlation coefficients between WM-PVS/BG-PVS, WM-PVS/BS-PVS, and BG-PVS/BS-PVS were 0.67, 0.61, and 0.59 (all p < 0.001). In the adjusted models, BG-PVS were associated with lacunes (p = 0.034), WMHs (p = 0.006), and microbleeds (p = 0.017); WM-PVS with lacunes (p = 0.003); while BS-PVS showed no associations. The WM/BG-PVS ratio was associated with lacunes (p = 0.018) and the PSQI (p = 0.046). Conclusions: PVS burdens in different regions are highly correlated in patients with RSSI but with different SVD patterns. Sleep quality impairment might affect waste removal mechanisms differently in the WM and BG regions. Full article

Carnitine palmitoyltransferase 1b (Cpt1b) is a crucial rate-limiting enzyme in fatty acid metabolism, but its role and mechanism in early cardiac development remains unclear. Here, we show that cpt1b regulates cardiomyocyte proliferation during zebrafish development. Knocking out entire cpt1b coding sequences leads to impaired cardiomyocyte proliferation, while cardiomyocyte-specific overexpression of cpt1b promotes cardiomyocyte proliferation. RNA sequencing analysis and pharmacological studies identified glutamine synthetase as a key downstream effector of cpt1b in regulating cardiomyocyte proliferation. Our study elucidates a novel mechanism whereby cpt1b promotes zebrafish cardiomyocyte proliferation through glutamine synthetase, which provides new perspectives on the significance of fatty acid metabolism in heart development and the interplay between fatty acid and amino acid metabolic pathways.

Two-dimensional transthoracic echocardiography (2D TTE) and two-dimensional transesophageal echocardiography (2D TEE) are regarded as the main imaging techniques for the assessment of degenerative mitral valve regurgitation (DMVR). However, describing the complex morphology of DMVR with 2D TTE and 2D TEE remains at the very least challenging. Three-dimensional (3D) TEE is an ideal technique for illustrating the extremely variable morphology of DMVR, providing images of unparalleled quality in terms of anatomical detail. In this review, we describe the key role of 3D TEE in various morphological scenarios that reflect everyday experiences in an echocardiographic laboratory. We also discuss the growing role of 3D TEE in mitral valve (MV) transcatheter edge-to-edge repair (TEER) and new modalities such as photorealistic and transparent displays, surface rendering parametric color maps, new algorithms for MVR quantification, and the potential role of new mini-TEE probes in adult patients with DMVR.

Symptomatic aortic stenosis and frailty reduce health-related quality of life (HrQoL). Transcatheter aortic valve implantation (TAVI) in patients at high to extreme risk has been proven to have a beneficial effect on HrQoL. Currently, TAVI is also considered in patients at intermediate risk. Our meta-analysis investigates whether benefits to HrQoL after TAVI is more pronounced in frail patients and patients at high to extreme vs. intermediate surgical risk. A systematic search of the literature was performed in November 2021 and updated in November 2023 in PUBMED, EMBASE, and the Cochrane Controlled Trials Register. Statistical analysis was performed according to the inverse variance method and the random effects model. A total of 951 studies were assessed, of which 19 studies were included. Meta-analysis showed a mean increase in the Kansas City Cardiomyopathy Questionnaire (KCCQ) score of 29.6 points (6.0, 33.1) in high to extreme risk patients versus 21.0 (20.9, 21.1) in intermediate risk patients (p < 0.00001) and 24.6 points (21.5, 27.8) in frail patients versus 26.8 (20.2, 33.4) in the general TAVI population (p = 0.55). However, qualitative analyses of non-randomized studies showed the opposite results. In conclusion, TAVI improves HrQoL more in high to extreme than intermediate risk patients. Frailty’s impact on HrQoL post-TAVI is inconclusive due to varying outcomes in RCTs vs. non-RCTs. Full article

Ventricular pre-excitation (VP) is a cardiac disorder characterized by the presence of an accessory pathway (AP) that bypasses the atrioventricular node (AVN), which, although often asymptomatic, exposes individuals to an increased risk of re-entrant supraventricular tachycardias and sudden cardiac death (SCD) due to rapid atrial fibrillation (AF) conduction. This condition is particularly significant in sports cardiology, where preparticipation ECG screening is routinely performed on athletes. Professional athletes, given their elevated risk of developing malignant arrhythmias, require careful assessment. Early identification of VP and proper risk stratification are crucial for determining the most appropriate management strategy and ensuring the safety of these individuals during competitive sports. Non-invasive tools, such as resting electrocardiograms (ECGs), ambulatory ECG monitoring, and exercise stress tests, are commonly employed, although their interpretation can sometimes be challenging. This review aims to provide practical tips and electrocardiographic clues for detecting VP beyond the classical triad (short PR interval, delta wave, and prolonged QRS interval) and offers guidance on non-invasive risk stratification. Although the diagnostic gold standard remains invasive electrophysiological study, appropriate interpretation of the ECG can help limit unnecessary referrals for young, often asymptomatic, athletes.

Background: MRI (magnetic resonance imaging) represents the diagnostic image modality of choice in several conditions. With an increasing number of patients requiring MRI for diagnostic purposes, the issue of safety in patients with cardiac implantable electronic devices (CIED) undergoing this imaging modality will play an ever more important role. The purpose of this study was to assess the safety and device function following MRI in an unrestricted real-world cohort of patients with a wide array of cardiac devices. Methods: We conducted a retrospective single-center study including 1010 MRI studies conducted in adult patients (≥18 years) with an implanted CIED treated in the University Hospital of Munich (LMU) between July 2012 and March 2024. Patients with non-MR conditionally labeled leads, abandoned or epicardial leads, as well as lead fragments, were included for analysis. Results: Across a total of 1010 MRIs (920 total MR-conditional device generators) performed in patients with an implanted CIED, there were no deaths, reports of discomfort, palpitations, heating, or ventricular arrythmias in the 24 h following MRI. Only 2/1010 MRIs were followed by a reported atrial arrhythmia within 24 h, both in patients with an MR-conditional pacemaker (PM) device without an abandoned lead. No significant changes in device function following MRI from baseline were observed across all included CIEDs. Lastly, no instances of severe malfunction, such as generator failure, loss of capture, electrical reset, or inappropriate inhibition of pacing, were found in post-MRI interrogation reports across all MRI studies. Conclusions: Based on the analysis of 1010 MRIs undergone by patients with CIEDs, following standardized device interrogation, manufacturer-advised device programming, monitoring of vital function, and manufacturer-advised reprogramming, MRI can be performed safely and without adverse events or changes in device function.

Children and adolescents (C&As) with congenital heart defects (CHDs) have decreased functional capacity and executive functioning (EF) due to brain abnormalities and decreased cerebral perfusion. Exercise may improve EF via increased cognitive demands and cerebral blood supply. The purpose of this review was to identify evidence describing the impact of physical activity (PA) interventions on EF in C&As with CHDs. The following databases were searched from 2000 to 2024: MEDLINE, EMBASE, CINAHL, Scopus, CENTRAL, and PsycInfo. The inclusion criteria consisted of participants aged from birth to 18 years with CHD, interventions related to PA, and EF as an outcome measure. Articles were excluded if adults were included, translation to English was impossible, and full access was unavailable. Of 613 initial articles, 3 were analyzed, with only 1 meeting all inclusion criteria. The included study found significant improvements in self-reported cognitive functioning and parent-reported social functioning after 12 weeks of aerobic exercise in children aged 10–15 years with CHDs. Common themes among the reviewed articles indicated that EF remains impaired throughout the lifespan, children have unique interventional and developmental needs, and research remains limited despite theoretical benefits. Further investigation of the effect of PA on EF in C&As with CHDs is needed. Full article

Statins also increase the risk of rhabdomyolysis, which is often minimized in comparison with large relative risk reductions of cardiovascular disease reported in clinical trials. By contrast, absolute risk reductions of cardiovascular disease are often clinically insignificant and unreported in statin clinical trials. Additionally, cytotoxic effects of statins inhibit cancer cell proliferation and reduce cancer risk, but other studies found that statins are carcinogenic. Due to an inverse association between incidence of cancer and atherosclerosis, the indication to prescribe statins likely biases the association of statins with cancer prevention. Dietary patterns associated with atherosclerosis and cancer contain inverse amounts of cholesterol and phosphate, an essential mineral that stimulates tumorigenesis. Accordingly, lower cancer risk is associated with high dietary cholesterol intake and increased risk of atherosclerosis. Furthermore, serum is exposed to excessive inorganic phosphate that could increase cancer risk as rhabdomyolysis induced by statins releases phosphate from skeletal muscle breakdown. Increased risk of comorbid conditions associated with statins may share the mediating factor of phosphate toxicity. More research is warranted on statins in the cause and prevention of cancer.

The developmental changes in the excitation–contraction mechanisms of the ventricular myocardium of small animals (guinea pig, rat, mouse) and their sympathetic regulation will be summarized. The action potential duration monotonically decreases during pre- and postnatal development in the rat and mouse, while in the guinea pig it decreases during the fetal stage but turns into an increase just before birth. Such changes can be attributed to changes in the repolarizing potassium currents. The T-tubule and the sarcoplasmic reticulum are scarcely present in the fetal cardiomyocyte, but increase during postnatal development. This causes a developmental shift in the Ca²⁺ handling from a sarcolemma-dependent mechanism to a sarcoplasmic reticulum-dependent mechanism. The sensitivity for beta-adrenoceptor-mediated positive inotropy decreases during early postnatal development, which parallels the increase in sympathetic nerve innervation. The alpha-adrenoceptor-mediated inotropy in the mouse changes from positive in the neonate to negative in the adult. This can be explained by the change in the excitation–contraction mechanism mentioned above. The shortening of the action potential duration enhances trans-sarcolemmal Ca²⁺ extrusion by the Na⁺-Ca²⁺ exchanger. The sarcoplasmic reticulum-dependent mechanism of contraction in the adult allows Na⁺-Ca²⁺ exchanger activity to cause negative inotropy, a mechanism not observed in neonatal myocardium. Such developmental studies would provide clues towards a more comprehensive understanding of cardiac function. Full article

The flow path of vertebrate hearts has a looped configuration characterized by curved (sigmoid) and twisted (chiral) components. The looped heart design is phylogenetically conserved among vertebrates and is thought to represent a significant determinant of cardiac pumping function. It evolves during the embryonic period of development by a process called “cardiac looping”. During the past decades, remarkable progress has been made in the uncovering of genetic, molecular, and biophysical factors contributing to cardiac looping. Our present knowledge of the functional consequences of cardiac looping lags behind this impressive progress. This article provides an overview and discussion of the currently available information on looped heart design and its implications for the pumping function. It is emphasized that: (1) looping seems to improve the pumping efficiency of the valveless embryonic heart. (2) bilaterally asymmetric (chiral) looping plays a central role in determining the alignment and separation of the pulmonary and systemic flow paths in the multi-chambered heart of tetrapods. (3) chiral looping is not needed for efficient pumping of the two-chambered hearts of fish. (4) it is the sigmoid curving of the flow path that may improve the pumping efficiency of lower as well as higher vertebrate hearts. Full article

Congenital heart disease (CHD) is the most common major congenital anomaly, affecting one in every 100 live births. Whereas over 90% of children born with CHD in low- and middle-income countries cannot access the care they need, early detection, advances in management, and financial risk protection have resulted in over 90% of children with CHD in high-income countries surviving into adulthood. Despite the presence of universal health coverage, barriers to accessing high-quality cardiovascular and non-cardiovascular care for CHD remain common. Lower socioeconomic status has been associated with differential access to cardiac care and poorer outcomes across multiple cardiovascular conditions and subspecialties. In this review article, we describe the relationship between socioeconomic status and access to CHD care in countries with universal health coverage models. We further evaluate notable challenges and opportunities to improve equitable, high-quality CHD care in these countries. Full article

The evaluation of the left atrial (LA) size using the LA volume index (LAVI) is clinically relevant due to its prognostic significance in various conditions. Nonetheless, adding a LA function assessment to the LAVI provides further clinical and prognostic information in different cardiovascular (CV) diseases. The assessment of LA function by echocardiography primarily includes volumetric measurements (LA ejection fraction [LAEF]), tissue Doppler imaging (TDI) (mitral annular late diastolic velocity [a’]), and speckle-tracking methods, such as LA longitudinal reservoir strain (LA strain). This review analyzes and discusses the current medical evidence and potential clinical usefulness of these different methods to analyze LA function. Full article

The process of coronary calcification represents one of the numerous pathophysiological mechanisms involved in the atherosclerosis continuum. Optical coherence tomography (OCT) represents an ideal imaging modality to assess plaque components, especially calcium. Different calcification patterns have been contemporarily described in both early stages and advanced atherosclerosis. Microcalcifications and spotty calcifications correlate positively with macrophage burden and inflammatory markers and are more frequently found in the superficial layers of ruptured plaques in acute coronary syndrome patients. More compact, extensive calcification may reflect a later stage of the disease and was traditionally associated with plaque stability. Nevertheless, a small number of culprit coronary lesions demonstrates the presence of dense calcified plaques. The purpose of the current paper is to review the most recent OCT data on coronary calcification and the interrelation between calcification pattern and plaque vulnerability. How different calcified plaques influence treatment strategies and associated prognostic implications is of great interest. Full article

Cardiac amyloidosis is the most frequent infiltrative disease caused by the deposition of misfolded proteins in the cardiac tissue, leading to heart failure, brady- and tachyarrhythmia and death. Conduction disorders, atrial fibrillation (AF) and ventricular arrhythmia (VA) significantly impact patient outcomes and demand recognition. However, several issues remain unresolved regarding early diagnosis and optimal management. Extreme bradycardia is the most common cause of arrhythmic death, while fast and sustained VAs can be found even in the early phases of the disease. Risk stratification and the prevention of sudden cardiac death are therefore to be considered in these patients, although the time for defibrillator implantation is still a subject of debate. Moreover, atrial impairment due to amyloid fibrils is associated with an increased risk of AF resistant to antiarrhythmic therapy, as well as recurrent thromboembolic events despite adequate anticoagulation. In the last few years, the aging of the population and progressive improvements in imaging methods have led to increases in the diagnosis of cardiac amyloidosis. Novel therapies have been developed to improve patients’ functional status, quality of life and mortality, without data regarding their effect on arrhythmia prevention. In this review, we consider the latest evidence regarding the arrhythmic risk stratification of cardiac amyloidosis, as well as the available therapeutic strategies. Full article

Objective: To study possible determinants of longevity in a cohort of middle-aged men followed for 61 years until extinction using measurements taken at baseline and at years 31 or 61 of follow-up. Material and Methods: In 1960, two rural cohorts including a total of 1712 men aged 40–59 years were enrolled within the Italian section of the Seven Countries Study of Cardiovascular Diseases, and measurements related to mainly cardiovascular risk factors, lifestyle behaviors, and chronic diseases were taken at year 0 and year 31 of follow-up (when only 390 could be examined). Multiple linear regression models were computed to relate personal characteristics with the length of survival in both dead men and survivors. Results: Baseline cardiovascular risk factors, smoking and dietary habits, and chronic diseases (taken at year 0 with men aged 40–59 years) were significant predictors of the length of survival both from year 0 to year 31 and from year 0 to year 61, but only chronic diseases were independent predictors for the period of 31 to 61 years. Significant predictors of survival using measurements taken at year 31 (age range 71 to 90 years) were only smoking and dietary habits and chronic diseases. Conclusions: During a lifetime of follow-up, the personal characteristics with continuous predictive power of survival were only lifestyle behaviors and major chronic diseases. Full article
