BACKGROUND: Pulmonary vein (PV) isolation is a well-established and effective treatment for paroxysmal atrial fibrillation (AF). However, in some patients, AF recurrence is driven by non-PV triggers. Identifying these triggers is crucial for achieving long-term ablation success, but their localization can be …

BACKGROUND: Pulsed-field ablation (PFA) has emerged as a novel energy source for pulmonary vein isolation in atrial fibrillation. Although generally safe, rare complications may occur during catheter manipulation in challenging pulmonary veins. CASE SUMMARY: A 71-year-old man underwent PFA with a circular-array …

BACKGROUND: Pulsed-field ablation (PFA) is a novel nonthermal technique that achieves myocardial ablation with high tissue selectivity and fewer complications than conventional thermal methods. Coronary vasospasm has been increasingly reported with the Farawave catheter, but data on the PulseSelect system are limited. …

ABSTRACT Background The efficacy of cryoballoon ablation (CBA) using a 28‐mm or 31‐mm cryoballoon for isolating the left common pulmonary vein (LCPV) remains poorly established. We aimed to evaluate procedural outcomes and long‐term follow‐up data of CBA for the LCPV using either …
