Heart mapping may improve ablation for persistent AF
NCT ID NCT03347227
First seen May 15, 2026 · Last updated May 20, 2026 · Updated 1 time
Summary
This study compares two catheter ablation methods for people with persistent atrial fibrillation (AF), a type of irregular heartbeat. About 500 participants will either receive standard treatment (isolating the pulmonary veins) or a tailored approach that also targets areas of low voltage in the heart. The goal is to see if the personalized method reduces repeat procedures and complications over 18 months.
