• 2-dimentional echocardiography was known to achieve a quantitive assessment of mitral valve area. However, several factors which were proper gain setting, correct localization of the mitral valve orifice and appropriated drawing of the perceived orifice were pointed out for accurate echocardiographic measurement of mitral valve orifice. Taking such factors into consideration, we measured the mitral valve areas echocardiographically in 31 patients with mitral stenosis and compared them with cardiac cathetelization data. There was a good correlation between the echocardiographically and the hemodynamically derived mitral valve areas, but the correlation was less good than previously reported (r=0.86). There were eleven patients who had been commissurotomied. Four patients of them were diagnosed to have restenosis of mitral valve and other seven patients were judged to have had good operative results. In this post-operative group, the correlation between the echocardiographically and the hemodynamically measured mitral valve areas was good, as that in non-operated group. However, wide difference of the calculated valve areas by two methods were founded in an individual patient with good operative result. Eleven patients had severe calcified mitral valve. The mitral orifice areas were successfully measured in all these patients. In this group, there was better correlation between the echocardiographically and the hemodynamically calculated mitral valve areas than in total patients (r=0.963). There was a good correlation between the diastolic decent rate (DDR) and the hemodynamically derived mitral valve areas (r=0.749). However, among the patients with small mitral orifice area less than 2cm^2 poor correlation between the DDRs and the cathetelization valve areas was obtained (r=0.345). 2-dimentional echocardiography is an accurate noninvasive method to measure the mitral valve area in patient with mitral stenosis, but there appear to be potential limitations ascribed to the very echocardiographic and hemodynamic methods to get better correlation than that of previous reports.
