Four hundred and twenty-five patients underwent mitral valvotomy between 1960 and 1979, the majority by the closed method. Thirty-two patients required another operation for mitral restenosis. There was high incidence of reoperation after the 6th and 7th years (23.3%) and after the 9th and 10th years (26.4%) postoperatively. Sixteen patients (47%) with restenosis underwent a second closed mitral valvotomy with a satisfactory result, 12 patients (35.4%) required valve replacement, and 6 patients (17.6%) had an open valvotomy. Another valvotomy for pure mitral restenosis can give satisfactory results, but where the valve is severely deformed or incompetent, valve replacement is preferred.
1960年至1979年间，425例患者接受了二尖瓣切开术，大多数采用闭式手术。32例患者因二尖瓣再狭窄需要再次手术。术后第6年和第7年（23.3%）以及第9年和第10年（26.4%）再次手术的发生率较高。16例（47%）再狭窄患者接受了第二次闭式二尖瓣切开术，效果满意；12例（35.4%）患者需要瓣膜置换；6例（17.6%）患者接受了直视二尖瓣切开术。单纯二尖瓣再狭窄再次行二尖瓣切开术可取得满意效果，但如果瓣膜严重变形或功能不全，则首选瓣膜置换术。
