Abstract

Background: A novel balloon-in-basket catheter integrated into a mapping system may advance pulsed field ablation (PFA) of atrial fibrillation (AF) with demonstrated deeper lesions, less hemolysis, and promising initial clinical experience. Objectives: The goal of this study was to assess the 1-year clinical outcomes of the balloon-in-basket PFA system. Methods: The multicenter VOLT-AF IDE Clinical Study enrolled patients with symptomatic, paroxysmal (PAF), and persistent AF (PeAF) . Pulmonary vein isolation (PVI) was performed with the investigational system. The primary effectiveness endpoint was acute PVI and 12-month freedom from atrial arrhythmia, antiarrhythmic escalation/initiation, c..
