Study start date: May 1, 2009

Actual date on which the first participant was enrolled.

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

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

45 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Case-only

These studies focus only on individuals who have a specific disease. Researchers examine patterns—often genetic or environmental—to uncover what might be linked to the condition.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
