Summary

This study tests if using a special energy device (radiofrequency ablation) during planned open-heart surgery can safely stop long-lasting atrial fibrillation (AFib). About 160 people with persistent AFib who need heart surgery for other reasons will take part. The goal is to see if the procedure can keep the heart in normal rhythm without needing long-term medication.
