The echocardiographic data (the amplitude of the mitral echogram, the velocity of the E to F slope and the dimension of the left atrium) of 12 patients with mitral stenosis were compared with hemodynamic data obtained during a cardiac catheterization (the mitral valve area and the peak left ventricular filling rate, expressed in millimeters/second [dv/dtD] and normalized by the end-diastolic volume [dv/dtD/VTD seg-1]). None of the echocardiographic variables showed a good correlation with the hemodynamic indices. It is concluded that echocardiography is a useful total in the diagnosis of mitral stenosis, but at the same time there is not a single echocardiographic sign which by itself evaluate correctly the severity of mitral stenosis.
对12例二尖瓣狭窄患者的超声心动图数据(二尖瓣回波图振幅、E至F斜率速度和左心房大小)与心导管检查时获得的血流动力学数据(二尖瓣瓣口面积和左心室峰值充盈率,以毫米/秒表示[dv/dtD],并通过舒张末期容积进行标准化[dv/dtD/VTD seg-1])进行了比较。没有一个超声心动图变量与血流动力学指标显示出良好的相关性。得出的结论是,超声心动图在二尖瓣狭窄的诊断中是一种有用的总体方法,但同时没有一个单一的超声心动图征象能够单独正确评估二尖瓣狭窄的严重程度。
