In order to define baseline descriptive criteria for the diagnosis of mitral valve prolapse with cross-sectional echocardiography, 49 patients undergoing catheterization were examined by a real-time, two-dimensional phased array echocardiographic imaging system. Angiography was used to separate patients into two distinct groups: 15 with normal mitral valve function and 34 with definite mitral valve prolapse. Systolic mitral leaflet and annulus motion were then observed in each patient and similarities and differences were noted between the two groups of patients. Correlative M-mode echocardiographic data were available in 37 patients. Certain two-dimensional echocardiographic findings restricted to the angiographically proven mitral valve prolapse group were defined: 1) posteriorly displaced coaptation of the leaflets, 2) systolic superior movement of one or both mitral leaflets above the level of the mitral ring, and 3) a systolic curling motion of the posterior mitral ring on its adjacent myocardium. One or more of these abnormalities were found in all 34 patients with angiographic mitral valve prolapse. When mitral valve prolapse does occur, the results of two-dimensional echocardiography would suggest that both leaflets are usually involved.
为了通过横断面超声心动图确定二尖瓣脱垂诊断的基线描述标准，使用实时二维相控阵超声心动图成像系统对49例接受心导管检查的患者进行了检查。血管造影用于将患者分为两个不同的组：15例二尖瓣功能正常，34例有明确的二尖瓣脱垂。然后观察每位患者的二尖瓣叶和瓣环的收缩期运动，并记录两组患者之间的异同。37例患者可获得相关的M型超声心动图数据。确定了某些仅限于血管造影证实的二尖瓣脱垂组的二维超声心动图表现：1）瓣叶对合点后移，2）一个或两个二尖瓣叶在收缩期高于二尖瓣环水平向上移动，3）二尖瓣后瓣环在其相邻心肌上的收缩期卷曲运动。在所有34例血管造影证实的二尖瓣脱垂患者中均发现了一种或多种这些异常。当确实发生二尖瓣脱垂时，二维超声心动图的结果表明两个瓣叶通常均受累。
