[An evaluation of long-term results of closed commissurotomy of mitral stenosis].
Closed mitral commissurotomy was performed in 206 consecutive cases with mitral stenosis from 1965 to 1987. Follow-up study from 8 months to 22 years showed that both early and long term postoperative results were satisfactory for mitral stenosis even in cases combined with mild mitral regurgitation. The long-term survival rate of this group of patients was 95.58% and the average time of maintenance of cardiac function classes I and II was 10.83 +/- 2.11 years. The influence of valvular calcification or high pulmonary arterial pressure on long-term effects was not serious, but preoperative atrial fibrillation or congestive cardiac failure might cause lead to poor results, indicating the benefit of early operation before their development. The peak period of restenosis with rapid decrease in cardiac function was 8-10 years postoperatively, and therefore more attention should be paid in this period to the decision of whether a reoperation is needed.
