NCT ID NCT05986526
First seen Apr 18, 2026 · Last updated Jun 19, 2026 · Updated 10 times
Summary
This study tests whether adding extra ablation to the back wall of the heart's left atrium improves outcomes for people with persistent atrial fibrillation (a type of irregular heartbeat). About 206 participants will receive either standard vein isolation or vein isolation plus back-wall ablation using a newer, safer energy method called pulsed-field ablation. The goal is to see which approach better prevents heart rhythm problems over one year.
