Special Issue Information

Dear Colleagues,

Dual antiplatelet therapy (DAPT) with aspirin and P2Y12 receptor inhibitors is the cornerstone of medical treatment after percutaneous coronary intervention (PCI) and stent implantation, aiming to decrease the risk of coronary stent-related and non-related thrombotic events. On the other hand, this strategy also increases the risk of bleeding over time. Of note, coronary thrombotic events and bleeding are associated with mortality risks of comparable magnitude after PCI, findings that should be taken into account in the risk/benefit calculations for extension versus discontinuation of DAPT. However, despite a large number of studies, the duration of DAPT remain unclear, in particular for patients at high risks, such as patients undergoing non-cardiac surgery, with history of malignancy or with recurrent coronary thrombotic events. Similarly, antithrombotic treatment is of paramount importance in patients undergoing transcatheter aortic valve replacement (TAVR) because of the increasing risk of valve thrombosis and thromboembolic events after procedure. The introduction in clinical practice of new generation devices and antithrombotic agents offer a broader spectrum of therapeutic options after PCI and TAVR procedures. This Special Issue will summarize new recommendations on optimal DAPT duration and decision-making tools in patients undergoing TAVR or PCI, based on original articles and systematic reviews.

The technique used at the time of implantation has a central role in determining the risk of thrombosis in bioresorbable vascular scaffolds (BRS). Different definitions of the “optimal” implantation technique exist, however. The impact of individual procedural characteristics on the risk of scaffold thrombosis (ScT) was evaluated in a single-center observational study that enrolled 657 patients (79% males, mean age 63 ± 12 years) with 763 lesions who received a total of 925 BRS for de novo lesions. During a median 1076 (762–1206) days’ follow-up there were 28 cases of thrombosis. Independent predictors of ScT included the use of predilatation balloons bigger than the nominal BRS diameter (hazard ratio (HR) = 0.4 (0.16–0.98), p = 0.04), sizing (implantation in vessels with reference vessel diameter >3.5 mm or <2.5 mm: HR = 5.71 (2.32–14.05), p = 0.0002) and the degree of vessel expansion (ratio of minimum lumen to reference vessel diameter, HR: 0.005 (0.0001–0.23), p = 0.007). In addition, a mild BRS oversizing (final BRS diameter to vessel diameter 1.14–1.28) was associated with a lower thrombosis risk, whereas undersizing and more severe oversizing (final BRS diameter to vessel diameter <1.04 and >1.35, respectively) were associated with an increased risk of ScT (HR = 0.13 (0.02–0.59), p = 0.0007). In conclusion, different components of the “optimal” technique have different impacts on the risk of BRS thrombosis. Besides predilatation with a balloon larger than the BRS diameter, correct vessel size selection and a mild to moderate oversizing appear to be protective. Full article

Circulating brain-derived neurotrophic factor (BDNF) predicts survival rate in patients with coronary artery disease (CAD). We examined the relationship between BDNF and renalase before and after percutaneous coronary intervention (PCI) and the role of renalase in patients with CAD. Serum BDNF and renalase levels were determined using blood samples collected before and after PCI. Incident myocardial infarction, stroke, and mortality were followed up longitudinally. A total of 152 patients completed the assessment. BDNF levels were not significantly changed after PCI compared to baseline levels (24.7 ± 11.0 vs. 23.5 ± 8.3 ng/mL, p = 0.175), although renalase levels were significantly reduced (47.5 ± 17.3 vs. 35.9 ± 11.3 ng/mL, p < 0.001). BDNF level before PCI was an independent predictor of reduction in renalase (95% confidence interval (CI): −1.371 to −0.319). During a median 4.1 years of follow-up, patients with serum renalase levels of ≥35 ng/mL had a higher risk of myocardial infarction, stroke, and death than those with renalase of <35 ng/mL (hazard ratio = 5.636, 95% CI: 1.444–21.998). In conclusion, our results show that serum BDNF levels before PCI were inversely correlated with the percentage change in renalase levels after PCI. Nevertheless, post-PCI renalase level was a strong predictor for myocardial infarction, stroke, and death. Full article

Transcatheter aortic valve implantation (TAVI) has emerged as an important alternative to surgical aortic valve repair (SAVR) for patients with severe aortic stenosis. This rapidly advancing field has produced new-generation devices being delivered with small delivery sheaths, embolic protection devices and improved retrieval features. Despite efforts to reduce the rate of thrombotic complications associated with TAVI, valve thrombosis and cerebral ischaemic events post-TAVI continue to be a significant issue. However, the antithrombotic treatments utilised to prevent these dreaded complications are based on weak evidence and are associated with high rates of bleeding, which in itself is associated with adverse clinical outcomes. Recently, experimental data has shed light on the unique mechanisms, particularly the complex haemodynamic changes at sites of TAVI, that underpin the development of post-TAVI thrombosis. These new insights regarding the drivers of TAVI-associated thrombosis, coupled with the ongoing development of novel antithrombotics which do not cause bleeding, hold the potential to deliver newer, safer therapeutic paradigms to prevent post-TAVI thrombotic and bleeding complications. This review highlights the major challenge of post-TAVI thrombosis and bleeding, and the significant issues surrounding current antithrombotic approaches. Moreover, a detailed discussion regarding the mechanisms of post-TAVI thrombosis is provided, in addition to an appraisal of current antithrombotic guidelines, past and ongoing clinical trials, and how novel therapeutics offer the hope of optimizing antithrombotic strategies and ultimately improving patient outcomes.
