Introduction Pulsed-field ablation (PFA) is a new, non-thermal ablation modality, which uses electrical impulses for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF). The study presents the experience of a tertiary cardiac centre in the UK in terms of safety and acute efficacy for a pentaspline, multi-electrode PFA catheter. Methods and results A local registry of patients who had PVI using PFA with Farapulse™ PFA ablation system (Boston Scientific, Menlo Park, CA, USA) was prospectively observed and analysed. A total of 66 patients underwent PVI ablation with PFA between March 2023 and January 2024. 45 of them (68.1%) were male and the mean age of the group was 62.4 years. The patients were equally divided between paroxysmal and persistent atrial fibrillation. 14 (21.2%) patients had tachycardia-induced cardiomyopathy with LVEF Conclusion This local registry data from a high-volume tertiary electrophysiology centre demonstrated a high acute PVI success rate with a safety profile comparable to existing modalities and short procedure times in a real-world AF patient population.
