Incidence, distribution, and electrogram characteristics of endocardial-epicardial connections identified by ultra-high-...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

The left atrial posterior wall (LAPW) can be a target for atrial fibrillation (AF) catheter ablation but is sometimes difficult to completely isolate due to the presence of endocardial-epicardial connections. We aimed to investigate the incidence and distribution of epicardial residual connections (epi-RCs) and the electrogram characteristics at ep...

Technological advances in ventricular tachycardia catheter ablation: the relentless quest for novel solutions to old pro...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Several novel technologies allowing catheter ablation (CA) with a favorable safety/efficacy profile have been recently developed, but not yet extensively clinically tested in the setting of ventricular tachycardia CA. In this technical report, we overview technical aspects and preclinical/clinical information concerning the application of three nov...

Computed tomography-based device-sizing in Amplatzer Amulet left atrial appendage occlusion.

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Amplatzer Amulet is a frequently used device for left atrial appendage occlusion (LAAO). The current sizing protocol is based on the maximum diameter of the left atrial appendage (LAA) landing zone. However, mean, perimeter-, or area-derived diameter might be more accurate measures for device sizing. Retrospective analysis of 150 consecutive patien...

Persistence of left atrial thrombus in patients with hypertrophic cardiomyopathy and atrial fibrillation.

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

We recently demonstrated that patients with atrial fibrillation (AF) and hypertrophic cardiomyopathy (HCM) have an increased risk of left atrial (LA) thrombus. In this study, we aimed to evaluate thrombus management, thrombus persistence, and thromboembolic events for HCM and non-HCM patients with AF and LA thrombus. From a cohort of 2,155 AF patie...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Hitherto, lumen less leads (LLLs) were routinely utilized for conduction system pacing (CSP). We report the largest experience using stylet-driven leads (SDLs) with a deflectable mapping catheter for CSP. Patients were prospectively and sequentially enrolled for CSP with SDL between June, 2021 and November, 2022 to (i) a novel deflectable mapping c...

High efficiency single-catheter workflow for radiofrequency atrial fibrillation ablation in the QDOT catheter era.

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

High-power short-duration (HPSD) ablation may improve the consistency and efficiency of pulmonary vein isolation (PVI). The novel QDOT Micro™ catheter (Biosense Webster, Inc.) with temperature feedback and microelectrodes aims to enhance PVI efficiency and safety. This study wants to evaluate the feasibility, safety, and efficiency of a standardize...

Success and complication rates of conduction system pacing: a meta-analytical observational comparison of left bundle br...

Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Left bundle branch area pacing (LBBAP) and His bundle pacing (HBP) are the main strategies to achieve conduction system pacing (CSP), but only observational studies with few patients have compared the two pacing strategies, sometimes with unclear results given the different definitions of the feasibility and safety outcomes. Therefore, we conducted...
