Echocardiographic studies were performed both before and after commissurotomy on fifteen subjects affected by non-calcified mitral stenosis. The amplitude CE of the anterior leaflet dis placement, the slope of the CD and EF intervals, the amplitude of the A-wave, the ratio FA/DE and the reciprocal position of the anterior and posterior leaflet echoes were measured on the echographic records. These data were compared with the values obtained in ten normal subjects. After commissurotomy, the slope of the CD interval and most evidently that of the EF interval increased (the last one by a factor of 3), and the area of the mitral opening was found to be more than 9% larger. The A-wave reappeared clearly in 30% of the operated patients, and the outline of the posterior leaflet was no longer inscribed in the anterior leaflet diastolic curve in all cases; the amplitude CE was unchanged.
对15例非钙化性二尖瓣狭窄患者在二尖瓣交界切开术前和术后均进行了超声心动图研究。在超声心动图记录上测量前叶位移的CE幅度、CD段和EF段的斜率、A波幅度、FA/DE比值以及前后叶回声的相对位置。将这些数据与10例正常受试者获得的值进行比较。二尖瓣交界切开术后，CD段斜率，最明显的是EF段斜率增加（后者增加了3倍），并且发现二尖瓣开口面积增大超过9%。30%的手术患者A波清晰再现，并且在所有病例中后叶轮廓不再嵌入前叶舒张期曲线内；CE幅度未改变。
