Can surgical radiofrequency treat atrial fibrillation in combination with organic heart disease?

  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.
