AIMS: Prolonged participation in exercise results in structural and electrical cardiac remodelling. The development of an athlete's heart is recognized as a risk factor for atrial arrhythmias. This study aims to evaluate the impact of athlete heart remodelling on the presentation of atrioventricular nodal re-entrant tachycardia (AVNRT). METHODS AND RESULTS: A retrospective analysis of an ablation database selecting all patients with an electrophysiologically confirmed diagnosis of AVNRT...

Aims: Action potential duration (APD) alternans is an established precursor or arrhythmia and sudden cardiac death. Important differences in fundamental electrophysiological properties relevant to arrhythmia exist between experimental models and the diseased in vivo human heart. To investigate mechanisms of APD alternans using a novel approach combining intact heart and cellular cardiac electrophysiology in human in vivo. Methods and results: We developed a novel approach combining intact heart electrophysiological mapping during cardiac surgery with rapid on-site data analysis to guide myocardial biopsies for laboratory analysis, thereby linking repolarization dynamics observed at the organ level with underlying ion channel expression...

Aims: Video-assisted thoracoscopic surgery (VATS) ablation has been advocated as a treatment option for non-paroxysmal atrial fibrillation (AF) in recent guidelines. Real-life data on its safety and efficacy during a centre's early experience are sparse. Methods and results: Thirty patients (28 persistent/longstanding persistent AF) underwent standalone VATS ablation for AF by an experienced thoracoscopic surgeon, with the first 20 cases proctored by external surgeons...

Aims : Bipolar electrogram (BiEGM)-based substrate maps are heavily influenced by direction of a wavefront to the mapping bipole. In this study, we evaluate high-resolution, orientation-independent peak-to-peak voltage (Vpp) maps obtained with an equi-spaced electrode array and omnipolar EGMs (OTEGMs), measure its beat-to-beat consistency, and assess its ability to delineate diseased areas within the myocardium compared against traditional BiEGMs on two orientations: along (AL) and across (AC) array splines...

Aims: Manual compression (MC), widely used to achieve venous access haemostasis, needs prolonged immobilization and extended time-to-haemostasis. Vascular closure devices (VCD) have been reported to have significantly shorter time to haemostasis and ambulation in arterial access-site management. The current study aimed to evaluate the safety and efficacy as well as rate of urinary tract complications in patients receiving MC vs. VCD for venous access-site closure. Methods and results: A total of 803 consecutive patients undergoing catheter ablation or left atrial appendage closure were classified into the VCD (n = 304) and the MC (n = 499) group, based on the methods used for haemostasis at the venous access site...

Aims: Mitral isthmus (MI) ablation is challenging. We hoped to close those conduction breakthrough sites (CBS) across the MI by elaborate mapping. Methods and results: After the initial linear ablation, elaborately mapping large areas above and below the MI line and inside the coronary sinus (CS) was sequentially performed to identify the CBS. The shortest distance from the CBS to the MI line was measured. The distant CBS (D-CBS) was identified as those CBS >5...

Aims: Our objectives were to compare effectiveness and long-term prognosis after epicardial thoracoscopic atrial fibrillation (AF) ablation vs. endocardial catheter ablation, in patients with prior failed catheter ablation or high risk of failure. Methods and results: Patients were randomized to thoracoscopic or catheter ablation, consisting of pulmonary vein isolation with optional additional lines (2007-2010). Patients were reassessed in 2016/2017, and those without documented AF recurrence underwent 7-day ambulatory electrocardiography...

Aims: Chronic pain at the cardiovascular implantable electronic device (CIED) generator or lead insertion site that is not otherwise manageable carries a IIA indication for extraction. However, limited data exist evaluating causes of pain and outcomes of extraction in eliminating pain. A multi-centre retrospective observational study was conducted to evaluate outcomes of patients undergoing device extraction for treatment of chronic device pain. Methods and results: Twenty-seven out of 2188 lead extraction candidates (1...

Aims: Atrial fibrillation (AF) ablation has made huge progress with respect to innovation, efficacy, and safety, however, complications are still present. Recent studies examined various predictors of complications. However, limited data exist regarding the role of a repeat procedure. Our aim was the prospective evaluation of the incidence and predictors of complications related to AF ablation procedures in consecutive patients, including repeat procedures. Methods and results: All ablation procedures for AF between January 2013 and December 2015 were analysed in our electrophysiology laboratory...

Aims: To perform a systematic outcome analysis in order to provide cardiologists and general pactitioners with more adequate information to guide their decision making regarding rhythm control. Totally thoracoscopic maze (TTmaze) for the treatment of atrial fibrillation (AF) is recommended as a Class 2a indication mainly based on single centre studies including small patient cohorts and inconsistent lesion sets. Methods and results: We studied consecutive patients undergoing TTmaze in three European referral centres (2012-15)...

Delivery of leads to the His bundle pacing region is most commonly performed with non-deflectable or deflectable sheaths and a His lead with an exposed helix. We present a technique where any pacing lead may be delivered to the His region utilizing a catheter- and snare-delivered approach.

Aims: Heart failure patients with advanced chronic kidney disease (CKD) may experience an increased rate of non-arrhythmic mortality due to associated comorbidities. We aimed to evaluate the risk of mortality without appropriate implantable cardioverter-defibrillator (ICD) shocks in this high-risk population. Methods and results: The study population comprised 3542 patients who received an ICD, were enrolled, and prospectively followed-up in the Israeli ICD registry...
