The importance of the echocardiogram in a study of mitral disorders has been analysed by examining 107 echocardiograms set against a clinical examination, an investigation of haemodynamic function (57), left-sided angiography (42), and/or examination at the time of operation (40). This study confirms the great diagnostic value of the echocardiographic findings in mitral stenosis (56 patients): the amplitude DE, the slope EF, the percentage of mid-diastolic closure, the echo from the valves, and the dimension of the left atria (P less than 0.001). This association remains valid if there is mitral incomptence as well as stenosis, or if there is also an aortic lesion, provided all the parameters are used. The degree of stenosis of the mitral orifice cannot be determined with sufficient certainty to allow surgical exploration to be undertaken solely on echocardiographic results, however the patients are selected (sinus rhythm, absence of calcification, mobile valve...). The echocardiographic diagnosis of the 17 cases of mitral incompetence was incomplete (except for rupture of the chords); the volume of the regurgitation is poorly appreciated.
通过对107份超声心动图进行分析，并与临床检查、血流动力学功能检查（57例）、左心造影（42例）和/或手术时检查（40例）相对照，研究了超声心动图在二尖瓣疾病研究中的重要性。本研究证实了超声心动图检查结果在二尖瓣狭窄（56例患者）中的巨大诊断价值：DE幅度、EF斜率、舒张中期关闭百分比、瓣膜回声以及左心房大小（P小于0.001）。如果同时存在二尖瓣反流和狭窄，或者还存在主动脉病变，只要使用所有参数，这种相关性仍然成立。然而，无论如何选择患者（窦性心律、无钙化、瓣膜活动度好……），仅根据超声心动图结果都无法足够确定地判断二尖瓣口狭窄程度，从而无法仅据此进行手术探查。17例二尖瓣反流的超声心动图诊断并不完整（除腱索断裂外）；反流容积难以准确评估。
