Special Issue Information

Dear Colleagues,

In recent years, substantial progress has been made in cardiac pacing and clinical electrophysiology. New technologies and innovative approaches have emerged and entered the clinical arena. Some have already become established treatment options, while others are still under development, and more evidence from clinical studies is warranted.

This Special Issue will provide state-of-the-art novel results of pacemaker and implantable cardioverter–defibrillator therapy, including conduction system pacing, leadless pacemakers, extravascular ICD and lead extraction. Moreover, we will provide a comprehensive state of the art of the invasive treatment of supraventricular and ventricular tachycardia, including new diagnostic tools and treatment modalities, as well as clinical results. This will also include cardio-neuro ablation for the treatment of non-cardiac syncope.

Researchers in the field of cardiac pacing and clinical electrophysiology are encouraged to submit review articles giving a critical appraisal of the current status of new, innovative approaches and novel technologies, as well as original articles presenting clinical outcome studies within the field.

Background: In patients requiring dual-chamber pacemaker (DDD) implantation, optimal atrial lead position remains a matter of debate. While most centers prefer implantation in the right atrial appendage position (Non-BB-P), due to a speculated favorable impact on atrial conduction characteristics, often, a Bachman bundle pacing (BB-P) is recommended. However, data investigating clinical outcomes in these patients are still rare. Methods: To evaluate this issue, in this retrospective single-center study, one-year clinical follow-up, pacemaker interrogations and available echocardiography findings in 301 consecutive patients (BB-P: age 76 ± 10 years, 46.7% female, n = 169; Non-BB-P: 77.6 ± 9 years, 50% female, n = 132, p = n.s.) scheduled for dual-chamber implantation were analyzed. Results: During follow-up, the incidence of atrial fibrillation (AF) remained similar in both groups (BB-P: 38.3%, n = 154 vs. Non-BB-P: 34.2%, n = 117 p = n.s.). However, we detected significantly more mode switch episodes in the BB-P group (BB-P: 51.9%, n = 154 vs. Non-BB-P: 38.8%, n = 116, p = 0.032). Furthermore, left ventricular functional parameters, including left ventricular ejection fraction (BB-P: 57.1 ± 8.4%, n = 60 vs. Non-BB-P: 56.0 ± 9.6, n = 45 p = n.s.) and incidence of diastolic dysfunction (BB-P: 55.2%, n = 67 vs. Non-BB-P: 38.3%, n = 47, p = n.s.), as well as the rate of left (BB-P: 58.8%, n = 68 vs. Non-BB-P: 42.0%, n = 50, p = n.s.) and right atrial dilatation (BB-P: 27.9%, n = 68 vs. Non-BB-P: 28.0%, n = 50 p = n.s.), were not significantly affected by the atrial lead position. However, stimulated p-waves were significantly shorter in BB-P vs. Non-BB-P (BB-P: 132.9 ± 23.7 ms, n = 127 vs. Non-BB-P: 139.6 ± 23.4 ms, n = 93, p = 0.031). Conclusions: In patients requiring dual-chamber implantation, the position of the atrial lead significantly altered atrial conduction, but this did not seem to affect left ventricular function parameters or the occurrence of atrial fibrillation within our follow-up period. Interestingly, we even detected more mode switch episodes in the BB-P group, hinting at an even proarrhythmic potential of BB-P. On the other hand, we found a decreased ventricular stimulation percentage in BB-P vs. Non-BB-P. Further studies should investigate the impact of Bachmann bundle pacing on clinical outcomes.

Background: Leadless pacemakers offer a safe and effective alternative pacing strategy. However, limited data are available for patients with end stage renal disease (ESRD), a population of significant relevance. Methods: Using the Nationwide Readmission Database, we extracted data from all adult patients with ESRD who underwent traditional transvenous or leadless pacemaker implantation between 2016 and 2021. We compared in-hospital mortality, 30-day readmission rates, complication rates, and healthcare resource utilization between the two cohorts. Results: A total of 6384 (81.2%) patients were included in the transvenous pacemaker cohort, and 1481(18.8%) patients were included in the leadless pacemaker cohort. In patients with ESRD, leadless pacemaker implantation was linked to higher in-hospital complications when compared to transvenous pacemakers. These included the need for blood transfusion (aOR 1.85, 95% CI 1.32–2.60, p < 0.01), vascular complications (aOR 3.6, CI 1.40–9.26, p = 0.01), and cardiac complications (aOR 4.12, CI 1.70–9.98, p < 0.01). However, there were no differences between the two groups in terms of in-hospital mortality and 30-day readmission rates. The median length of stay was longer for leadless pacemaker implantation than transvenous pacemaker implantation (5 days vs. 4 days, p < 0.01). The total hospitalization charges were also higher ($139,826 vs. $93,919, p < 0.01). Conclusions: Although previous studies have demonstrated lower long-term complication rates with leadless pacemakers than transvenous pacemakers, our analysis shows a higher risk of short-term in-hospital complications in ESRD patients, though no differences in in-hospital mortality and 30-day readmissions.
