PVI Alone vs PVI With Posterior Wall Isolation for Pulse-Field Ablation in Persistent AF

To date, no optimal treatment has been established to improve outcomes in patients with persistent atrial fibrillation. The safety and efficacy of pulsed-field ablation (PFA) have been demonstrated in several studies, and its clinical application is expanding. - In patients with persistent atrial fibrillation, can the addition of posterior wall isolation (PWI) following pulmonary vein isolation (PVI) using PFA reduce recurrence? Participants will: * Undergo either PVI alone or PVI with additional left atrial posterior wall isolation (PWI) * Visit the clinic to assess for recurrence of atrial tachyarrhythmias
