The object of the work was to disclose the possibilities of bimetric echocardiography in appraising the mobility of the mitral valve cusps in patients with mitral stenosis. The shape of the mitral cusp movement was studied in the longitudinal and transverse planes of the heart section. The results of the ultrasonic examinations were compared with the operative findings in 68 patients operated on for mitral stenosis. In satisfactory mobility of the valve, "sail-shaping" of the cusps is recorded in the longitudinal plane of the heart section and a concavity in the transverse plane in the period of diastole. In coarse fibrosis of the cusps, the diastolic movement of the surface of the anterior cusp is recorded as a displacement of a straight line which moves parallel to its initial position in the period of systole. Bimetric echocardiography makes it possible to determine exactly the character of the mitral valve lesion and determine the degree of mobility of the cusps in patients with mitral stenosis. This information may be decisive in choosing the method of surgical correction of the disease.
这项工作的目的是揭示双平面超声心动图在评估二尖瓣狭窄患者二尖瓣瓣叶活动度方面的可能性。在心脏切面的纵向和横向平面研究二尖瓣瓣叶运动的形态。将68例接受二尖瓣狭窄手术患者的超声检查结果与手术发现进行了比较。在瓣膜活动度良好时，在心脏切面的纵向平面可记录到瓣叶呈“帆状”，舒张期在横向平面呈凹陷。在瓣叶粗大纤维化时，前瓣叶表面的舒张期运动记录为一条直线的移位，该直线在收缩期平行于其初始位置移动。双平面超声心动图能够准确确定二尖瓣病变的特征，并确定二尖瓣狭窄患者瓣叶的活动度。这些信息对于选择该疾病的手术矫正方法可能具有决定性意义。
