Radiofrequency ablation maze procedure in the treatment of 66 patients with atrial fibrillation

AIM Modify Cox maze procedure and make it can be adopted in common use without complex technique and possible big bleeding after operation. METHODS We treated 66 cases of atrial fibrillation (AF) with rheumatic heart disease using radiofrequency ablation maze procedure as valve replacement were performed. 30 cases of 66 cases were male, 36 female, ages of the patients were from 30 to 58 years old (average 43.5 years). The duration of AF was from 1 year to 30 years (average 3.6 years). We adopted Shio Kosakai'smaze procedure route in radiofrequency ablation in principle. RESULTS 54 cases of 66 cases resumed sinus rhythm (82%), 9 patients remained AF, 2 patients turned to atrial flutter, 1 patient was junctional rhythm when the patients dischaged. CONCLUSION Radiofrequency ablation maze procedure is a simple, safe and effective method to treat atrial fibrillation.
