The clinical data of 57 cases of atrial fibrillation complicated by organic heart disease treated with bipolar radiofrequency ablation forceps from August 2009 to May 2012 were retrospectively analyzed. RESULTS: The procedures were successfully completed in this group of patients. The radiofrequency time ranged from 16 to 38 (24±4) min, the aortic block time ranged from 64 to 200 (126±36) min, and the extracorporeal circulation time ranged from 91 to 238 (150±37) min; the sinus heart rate at the end of the procedure and at discharge was 46 (79%) and 45 (78%) cases, respectively, and the sinus heart rate at 3, 6, and 12 months of follow-up was 41 (71%), The sinus heart rate was 41 (71%), 40 (69%) and 42 (72%) cases at 3, 6 and 12 months of follow-up, respectively. There were no procedural deaths or RF-related complications in the entire group. No permanent pacemakers were required in all patients. There was no significant difference between biventricular ablation and left atrial ablation alone. Conclusion: This method is feasible and has satisfactory results, but attention should be paid to the indications. The success rate of conversion to sinus with a left atrium greater than 60 and a long duration of atrial fibrillation is low.
