Clinical Analysis Bipolar Radiofrequency Maze Operation For Atrial Fibrillaton During Concomitant Cardiac Surgery

Objective:the retrospective analysis about bipolar radiofeqneney maze operation for atrial fibrillation undergoing cardiac surgery 46 patients, The purpose of was to examine the effectiveness of ganglia plexus for treatment of atrial fibrillation.Methods:From May 2008 to March 2009,46 patients underwent bipolar radiofrequency maze operation for atrial fibrillation combined with other cardiac procedures. One is ablation of ganglia plexus with the modified Cox maze procedure was the traditional treatment of atrial fibrillation during cardiac surgery. The others only radiofeqneney maze operation for atrial fibrillation undergoing cardiac surgery. Include general clinical data, whether or not to be ablation of ganglia plexus, alteration of left auricle contractile function,and so on.Results:1.In the non-ablation of ganglia plexus 23 cases,17 patients was sinus rhythm when they leaved hospital.19 patients recover sinus rhythm over 12 months after operation. The rate of stable sinus rhythm (sSR) was 82.60%, In the ablation of ganglia plexus 23 cases,22 patients was sinus rhythm when they leaved hospital.22 patients recover sinus rhythm over 12 months after operation. The rate of stable sinus rhythm (sSR) was 95.65%.2.There was no difference in hospital day,apply breathing machine time,and complication after operation between them.3.There was a significant decrease in left atrial dimension and A peak wave appeared in all cases with sSR.Conclusion:Ablation of ganglia plexus when bipolar radiofeqneney maze operation for atrial fibrillation undergoing cardiac surgery is a safe and highly effective surgical option.
