CHARACTERIZATION OF ARRHYTHMIA SUBSTRATE TO ABLATE PERSISTENT ATRIAL FIBRILLATION (COAST-AF)

Summary

This study is comparing two ways of doing an ablation procedure for people with persistent atrial fibrillation. Half of the patients will receive a regular procedure and the other half will have some extra "mapping" done inside the heart for abnormal tissue scientists think may be responsible for AF and those areas would be ablated as well. Patients will not know which kind of procedure they receive. Patients are then followed by study staff every 6 months and wear a 14-day cardiac monitor which will be reviewed with the doctor.
