Atrial Fibrillation Ablation Clinical Trial
Official title:
Surgery After Previous Failed Catheter Ablation
Specific Aims: The primary objective of this registry is to determine the percentage of
patients who are free from atrial fibrillation (AF) at 6 and 12 months following a surgical
ablation procedure when the patient has a history of failing one or more previous catheter
based ablations for AF. The first 3 months following surgical ablation will be a blanking
period; any arrhythmia occurring during this time will not be used to determine success.
Primary Objectives:
1. Determine the percent success of surgical ablation for AF at 6, and 12 months both on
and off of antiarrhythmic drugs (AAD) following a failed catheter based ablation for AF
2. Record and evaluate all complications associated with the surgical procedure.
Secondary Objectives:
1. Evaluate usage of anticoagulants at 6, and 12 months.
2. Determine the percentage of Pulmonary Veins (PV) that were electrically isolated by
intra-operative, pre-surgical mapping
