title: The mid-term outcome of the Cox maze III procedure and complex concomitant cardiac surgery.
abstract: OBJECTIVE
  Many surgeons do not deal with atrial fibrillation or choose modifications of the maze procedure when performing additional cardiac surgery. The Cox maze III procedure as an adjunct to other sometimes very complex cardiac surgery was examined.
  
  
  METHODS
  40 patients (27 men), 36 to 76 years, underwent a full Cox maze III operation in combination with other cardiac surgery, reflecting the case mix of a modern practice. Permanent fibrillation was presented by 82%, the others suffering from persistent or paroxysmal fibrillation. Pre-operative duration of atrial fibrillation was 0.5 to 39 years. Follow-up was 22 to 82 months.
  
  
  RESULTS
  The 30-day mortality was 2.5%; there was one case of intra aortic balloon-pump, two re-operations because of bleeding (5%), and one re-operation because of systolic anterior motion of the anterior mitral leaflet. Follow-up was 95% complete. Late mortality was 2.5%. Five patients (14%) required postoperative pacemakers. Freedom of atrial fibrillation was 97%.
  
  
  CONCLUSIONS
  The addition of the Cox maze III procedure to other sometimes very complex cardiac surgery is safe and efficient in controlling atrial fibrillation.
