| Popis: | The study aim was to evaluate the safety and feasibility of radiofrequency ablation for the surgical treatment of permanent atrial fibrillation in patients with degenerative mitral valve disease.From August 2000 to August 2003, 40 consecutive patients (mean age 69.0 +/- 9.3 years) with permanent atrial fibrillation and degenerative mitral valve disease underwent surgical radiofrequency ablation in conjunction with 22 mitral valve repairs and 18 mitral valve replacements. The mean duration of chronic AF was 5.1 +/- 3.4 years. The completeness of follow-up was 100%. The mean follow-up time was 4.6 +/- 2.0 years (range 0 to 7.8 years).Thirty-day mortality was 2.5% (1 patient), the cause of death was cardiac failure. Cardiac failure and temporary A-V block were the most common postoperative complications. Both occurred in 10% (4 patients). No complication was related to the ablation procedure. At discharge, 65% (26/40) of the patients were in sinus rhythm. Overall incidence of sinus rhythm at the end of the follow-up was 56.4% (22/39).The 1-, 3- and 5-year survival was 97.5%, 91.8% and 85.9%, respectively.Mitral valve surgery combined with radiofrequency ablation is a safe and effective procedure in patients with permanent atrial fibrillation and degenerative mitral valve disease. The result is encouraging in restoring sinus rhythm, and an excellent postoperative survival rate can be achieved. |
