Cross-sectional echocardiography was performed on two patients with mitral regurgitation in whom M-mode echocardiographic findings were not specific for the etiology of mitral regurgitation. In one patient, flail motion of the free edge of the anterior mitral leaflet into the left atrium was demonstrated only by cross-sectional echocardiograms. In the second patient, the flail posterior mitral leaflet was suggested to be a result of bacterial endocarditis. Cross-sectional echocardiograms clearly identified a flail motion of a mass of vegetation attached to the posterior mitral leaflet. Thus, cross-sectional echocardiography can provide critical information in recognizing patients with a flail mitral leaflet.
对两名二尖瓣反流患者进行了横断面超声心动图检查，这两名患者的M型超声心动图检查结果对于二尖瓣反流的病因并无特异性。在一名患者中，仅通过横断面超声心动图显示二尖瓣前叶游离缘甩入左心房。在第二名患者中，二尖瓣后叶连枷样运动被认为是细菌性心内膜炎的结果。横断面超声心动图清晰地识别出附着于二尖瓣后叶的一团赘生物的连枷样运动。因此，横断面超声心动图在识别二尖瓣连枷样运动患者方面可提供关键信息。
