[Long-term evaluation of valvuloplastic surgery in congenital heart diseases].
Valvuloplastic surgery was performed on the 89 cases of congenital aortic and mitral regurgitation between 1966 and 1983. There were 4 operative deaths and 4 late deaths. Reoperation was performed on the 5 aortic and the 6 mitral cases due to residual regurgitation. In the same period, all 4 cases died after valve replacement for the congenital aortic and mitral regurgitation. Long-term evaluation over 3 years was done for the 35 cases of aortic regurgitation with ventricular septal defect (AR + VSD) and the 38 cases of congenital mitral regurgitation except endocardial cushion defect, who were treated by valvuloplastic surgery at the initial operation. Statistical studies on the cases with AR + VSD showed 100% actuarial survival rate, 83% reoperation free rate and 91% valve replacement free rate after 17 years. Of the cases with congenital mitral regurgitation, 95% survival rate and 78% reoperation free rate after 16 years were revealed. In conclusion, the author believes that the operative results and the long-term stability of valvuloplastic surgery for regurgitant valvular lesions associated with congenital heart diseases can be more improved by keeping the precise indication and using the appropriate valvuloplastic procedures for the individual cases.
