INTRODUCTION AND OBJECTIVES: Pulmonary vein (PV) isolation is one of the cornerstones of rhythm-control therapy for symptomatic atrial fibrillation (AF) patients. Pulsed field ablation (PFA) is a novel ablation modality that involves the application of electrical pulses causing cellular death, and it has preferential tissue specificity. In this study, we aimed to share a one-year single center experience of AF ablation with PFA. METHODS: Single center, retrospective study of consecutive patients undergoing PVI using the pentaspline PFA catheter between June 2022 and July 2023. Data on demographic, procedural, and electrocardiographic recurrence (assessed after a three-month blanking period) were analyzed. RESULTS: One hundred twenty-three consecutive patients were included (62±11 years, 59% male), with a mean CHA CONCLUSIONS: Pulsed field ablation for PVI and posterior wall ablation was an efficient and safe procedure with low rate of complications and high percentage of patients were free from AF in short-term follow-up. We need more studies to evaluate long-term success.
