[The long-term result of atrioventricular valvuloplasty and surgical technique]

The long-term follow-up study was performed on various atrioventricular valvuloplasties, and our special technique of annuloplasty was also described. In mitral stenosis, 10 and 20 years actuarial survival rates were 82 and 78% in CMC and 92 and 83% in OMC with statistically better result. Reoperation free rates at 10 and 20 years were 86 and 74% in CMC, and 87 and 73% in OMC, although statistically better result was shown in OMC at 28 years. In mitral regurgitation, 140 patients underwent surgery from 1990 to 1994. MVP was successful on 33 patients and the remained 107 patients underwent MVR with St. Jude Medical valve. Actuarial survival rates at 5 and 10 years were 94 and 78% in MVP, and 92 and 88% in MVR. Complication free rates at these periods were 88 and 74% in MVP, and 78 and 69% in MVR, showing no statistical difference. In tricuspid regurgitation. 166 cases underwent DeVega's annuloplasty with excellent result of reoperation free rate of 97% at 10 years.
