Early clinical observation of radiofrequency ablation during concomitant mitral valve replace surgery / 局解手术学杂志

ABSTRACT

Objective The purpose of this study was to investigate the early outcome of radiofrequency ablation for the treatment of atri-al fibrillation (AF) during concomitant mitral valve replace procedures. Methods From January 2013 to September 2014,43 patients with mitral valvular disease with atrial fibrillation were enrolled in this study. The cases were classified into underwent mitral valve replace surgery concomitant with atrial fibrillation radiofrequency ablation ( RFA group) or underwent only mitral valve replace surgery ( control group) . Re-sults There was no perioperative death and stroke. RFA group’ s time of Cardiopulmonary bypass was more longer than control group. The comparison between RFA and control groups revealed no differences in terms of bleeding,24 hours’ Pleural fluid volume,the mechanical ven-tilation time and time in intensive care unit. One week after the operation,20 cases (87%) in RAF group were sinus rhythm while it was 6 cases(30%) in control group. After a follow-up of one month,RAF group had 78% remaind sinus rhythm while it was 25% in control group. Conclusion Radiofrequency ablation for the treatment of atrial fibrillation ( AF) during concomitant mitral valve replace is safe and effective.
