Heart Scar-Guided ablation may cut AF recurrence
NCT ID NCT05794386
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether treating extra scar tissue in the heart's upper chamber, along with the standard vein isolation, can better control atrial fibrillation (AF) in people with persistent AF. About 204 adults with moderate scarring will be randomly assigned to standard treatment or the scar-guided approach. The main goal is to see if this reduces abnormal heart rhythm returning within a year.
