Surgical biatrial ablation of atrial fibrillation: initial results

Rev Bras Cir Cardiovasc. 2010 Jan-Mar;25(1):45-50. doi: 10.1590/s0102-76382010000100012.


Objective: To evaluate the results of intraoperative radiofrequency ablation with biatrial procedure in the treatment of chronic atrial fibrillation in patients with associated cardiac disease.

Methods: Between February 2008 and May 2009, 15 consecutive patients were underwent mitral valve procedure plus modified radiofrequency biatrial ablation of chronic atrial fibrillation. The mean age was 47.73 +/- 9.85 years and 60% were male. The mean left atrial diameter was 55.06 +/- 7.56 mm.

Results: There were no hospital mortality or complications related to radiofrequency ablation. The mean follow-up period was 7 +/- 4 months. At the time of hospital discharge nine (60%) patients were in sinus rhythm. After a mean follow-up period 11 (73.3%) were in sinus rhythm.

Conclusion: Intraoperative biatrial radiofrequency ablation is a safe and effective technique for the treatment of chronic atrial fibrillation, with satisfactory midterms outcomes in terms of conversion to sinus rhythm.
