AIMS: Our aim was to compare the long-term effects on rhythm and quality of life (QoL) after left atrial epicardial radiofrequency (RF) ablation vs. no ablation in patients undergoing cardiac surgery. METHODS AND RESULTS: Thirty-nine patients with ECG documented atrial fibrillation (AF) scheduled for coronary artery bypass grafting (CABG) with or without concomitant valve surgery were consecutively elected for epicardial RF ablation. Thirty-nine age- and gender-matched patients scheduled for CABG with or without concomitant valve surgery only and with documented AF served as controls. The follow-up after ablation was 32 +/- 11 months. The percentage of patients in sinus rhythm (SR) at long-term follow-up was 62 vs. 33% (P = 0.03) after ablation and no ablation, respectively. SR at 3 months was highly predictive of that at 32 months (sensitivity 95%, positive predictive value 86%). Long-term SR was associated with better QoL, fewer symptoms, higher ejection fraction, and smaller left and right atria than AF. CONCLUSION: SR at 3 months was highly predictive of long-term SR that was associated with clinical improvement when compared with patients still in AF. AF at 3 months did not preclude a later stabilization to SR.
