135 patients operated for stenosis of the mitral valve were observed and treated 10.3 years, on the average. Three years of this time belong to the preoperative period and 7.3 years to the postoperative one. For evaluating the degree of stenosis, several ultrasound cardiograms were made yearly. After the operation one ultrasound examination was made every year for observing progress. In order to examine the effect of penicillin metaphylaxis on the process of restenosis, the patients were classified into different groups. The best operative result was maintained if continuous postoperative treatment with penicillin was made.
对135例因二尖瓣狭窄接受手术的患者进行了平均10.3年的观察和治疗。其中3年为术前观察期，7.3年为术后观察期。为评估狭窄程度，每年进行多次超声心动图检查。术后每年进行一次超声检查以观察病情进展。为研究青霉素预防性治疗对再狭窄过程的影响，将患者分为不同组。如果术后持续使用青霉素治疗，可保持最佳手术效果。
