Posterior wall ablation by pulsed-field ablation - procedural safety, efficacy and findings on redo procedures.

ABSTRACT:

Background

The left atrial posterior wall is a potential ablation target in patients with recurrent atrial fibrillation despite durable pulmonary vein isolation or in patients with roof-dependent atrial tachycardia (AT). Pulsed-field ablation (PFA) offers efficient and safe posterior wall ablation (PWA), but available data is scarce.

Methods

Consecutive patients undergoing PWA using PFA were included. PWA was performed using a pentaspline PFA catheter and verified by 3D-electroanatomic mapping. Follow-up was performed using 7-day Holter-ECGs 3, 6, and 12 months after ablation. Recurrence of any atrial arrhythmia lasting more than 30 seconds was defined as failure. Lesion durability was assessed during redo procedures.

Results

PWA was performed in 215 patients (70% mal
