Summary

This study is a registry that collects information and blood samples from over 2,400 people with atrial fibrillation who are scheduled for a heart procedure called ablation. The goal is to learn which patients benefit most from the procedure and to better understand what causes atrial fibrillation. Participants are followed to see if their heart rhythm problems return after treatment.
