Summary

This study tests whether adding extra ablation to the standard procedure helps people with persistent atrial fibrillation (a type of irregular heartbeat). About 206 adults with this condition will receive either standard vein isolation or that plus posterior wall ablation using a newer, safer energy method. The goal is to see which approach better prevents heart rhythm problems over one year.
