Pulsed Field Ablation for PVI in AF – American College of Cardiology

Introduction Electrical isolation of the pulmonary veins (PV) is the cornerstone of catheter ablation strategies for both paroxysmal and persistent atrial fibrillation (AF). Currently available energy modalities such as radiofrequency, cryotherapy, and laser-based PV isolation (PVI) are limited by long-term PV reconnection rates that, at best, range from 22% to 38%,1,2…
