New heart ablation method aims to stop AFib recurrence
NCT ID NCT07587541
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a new catheter ablation system using pulsed field energy can better control persistent atrial fibrillation (AF) by targeting low-voltage areas in the heart and isolating the superior vena cava, in addition to standard pulmonary vein isolation. About 618 adults with persistent AF will be randomly assigned to different ablation strategies. The goal is to see which approach reduces the return of irregular heart rhythms at 6 and 12 months.
