摘要
OBJECTIVES: To determine the effectiveness of a simplified surgical treatment method for atrial fibrillation (AF). @@@ METHODS: Between September 2012 and October 2013, 120 patients (mean age, 52.3 +/- 8.8 years) underwent valve surgery and concomitant bipolar radiofrequency ablation for the treatment of AF. Patients were randomized to a Cox maze IV procedure (CMP-IV) group (n = 60) or a modified CMP-IV (MCMP-IV) group (n = 60). Freedom from AF was defined as freedom from any left atrial arrhythmia lasting < 30 s and no requirement of antiarrhythmic drugs after 6 months. Data were recorded at postoperative follow-up examinations, which were scheduled at 1, 3, 6 and 12 months, and annually thereafter. @@@ RESULTS: No ablation-related complications occurred in either group. The mean ablation time was longer in the CMP-IV group than in the MCMP-IV group (18.5 +/- 1.7 vs 16.6 +/- 1.6 min, P < 0.001). The mean follow-up time was 32.4 +/- 3.6 months (range, 26-39 months). Freedom from AF tended to be higher, but not significantly so, among the MCMP-IV group than among the CMP-IV group over the entire follow-up period. @@@ CONCLUSIONS: The MCMP-IV is an effective surgical procedure for the treatment of AF. In certain patients, such as those with anatomic variations of the pulmonary veins, the MCMP-IV is simpler than the CMP-IV.
