Extra ablation may keep atrial fibrillation away longer

NCT ID NCT02150902

First seen May 04, 2026 · Last updated May 15, 2026 · Updated 2 times

Summary

This study tests whether adding extra ablation sites during a standard heart procedure for atrial fibrillation (AF) can lower the chance of AF coming back. About 400 adults with intermittent AF will be randomly assigned to receive either the standard ablation plus a drug to check for missed spots, or the standard ablation plus an extra ring of ablation. Researchers will track heart rhythm and complications for at least one year.
