William H. Sauer, MD, FHRS, CCDS, Brigham and Women's Hospital is joined by guest Amin Al-Ahmad, MD, FHRS, CCDS, Texas Cardiac Arrhythmia Institute and Jorge Romero, Jr., MD, FHRS, Brigham and Women's Hospital to discuss how Pulsed-field ablation (PFA) is a novel nonthermal ablation technology with high procedural safety and efficiency for pulmonary vein isolation (PVI). Premarket data showed high PVI durability during mandatory remapping studies. Data on lesion durability in real-world patients with clinically indicated redo procedures are scarce. In this episode of The Lead, we discuss why and how this study sought to report PVI durability rates in patients undergoing a clinically indicated redo procedure after an index PVI using PFA.
