BACKGROUND: Data on combined permanent atrial fibrillation (pAF) surgery and coronary artery bypass grafting (CABG) and/or aortic valve replacement (AVR) are scarce, and the mid- and long-term effects on survival and cardiac rhythm are unknown. MATERIAL AND METHODS: In a prospective analysis 125 patients (Group I: CABG and/or AVR, n = 50; Group II: mitral valve [MV] surgery, n = 75) with pAF (> or = 6 months) underwent either concomitant monopolar (Group I: n = 20; Group II: n = 75) or bipolar (Group I: n = 30) radiofrequency (RF) ablation procedures. Group I patients had a significantly smaller left atrial (LA) size than Group II patients (LA-diameter: 47.7 +/- 4.6 vs. 58.2 +/- 6.1 mm; p < 0.01). Regular follow-up was performed from 3 to 36 months after surgery to assess survival, NYHA-class, and conversion rate to stable sinus rhythm (SR). RESULTS: Early mortality (< 30 days) of Group I patients was 0% (Group II: 2.7%), cumulative survival at long-term follow-up was 0.95 vs. 0.82 (p = 0.31) and NYHA-class improved significantly in both groups, particularly in cases with stable SR. At follow-up 80% of Group I patients had SR (Group II: 70%). In Group I patients the bipolar approach was associated with significantly shorter ablation procedure times compared to the monopolar procedure (12.1 +/- 3.4 vs. 18.9 +/- 1.6 min; p < 0.05). CONCLUSIONS: Concomitant pAF ablation surgery in CABG and/or AVR is safe and at least as effective as in MV surgery, presumably because severe LA enlargement is exceptionally rare in this group.
