Heart rhythm showdown: which ablation strategy wins for persistent AF?

NCT ID NCT05921734

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study tested two ways to treat persistent atrial fibrillation (a type of irregular heartbeat) using catheter ablation. In one group, doctors aimed to stop the abnormal rhythm during the procedure. In the other, they followed a preset plan and used electrical shock if needed. The trial included 480 adults having their first ablation. The goal was to see which approach led to fewer heart rhythm problems over 12 months.

Active substance

catheter ablation procedure

What this could lead to

If successful, this could help doctors choose the best ablation approach to reduce irregular heart rhythms in people with persistent atrial fibrillation.

What could go wrong

The trial is completed but results are not yet widely published. Ablation carries risks like bleeding, infection, or heart damage, and the best strategy may still depend on individual patient factors.
