Pulmonary Vein Isolation Using Pulsed Field Ablation With vs Without Posterior Wall Isolation in Patients With Symptomatic Persistent Atrial Fibrillation: The PIFPAF-PFA Randomized Clinical Trial.
Importance Pulmonary vein isolation (PVI) is less effective in persistent than in paroxysmal atrial fibrillation (AF). Objective To determine whether adding posterior left atrial wall isolation (PWI) to pulsed field ablation (PFA)-based PVI reduces atrial tachyarrhythmia in patients with persistent AF. Design, Sett...
