Abstract

Four patients with endocardial fibroelastosis were studied by two-dimensional and M-mode echocardiography. The two-dimensional echocardiography showed the characteristic echo from the abnormally thickened endocardium of the left ventricle in every case. Of the 4 cases, 2 were still suffering from congestive heart failure at the time of the study and the other 2 had been already free from clinical symptoms. In the former group, the ultrasonic findings revealed an enlargement of the left ventricle (large left ventricular dimension index) and poor movement of the anterior mitral leaflet which was indicated by a decrease in the diastolic descent rate. The latter group presented almost normal findings concerning the above points. The ultrasonic method is thus proved to be very useful for the diagnosis and evaluation of clinical conditions in cases of endocardial fibroelastosis.

摘要

对4例心内膜弹力纤维增生症患者进行了二维和M型超声心动图检查。二维超声心动图显示，每例患者左心室异常增厚的心内膜均有特征性回声。4例患者中，2例在研究时仍患有充血性心力衰竭，另外2例已无临床症状。在前一组中，超声检查结果显示左心室扩大（左心室尺寸指数大），二尖瓣前叶运动减弱，舒张期下降速率降低表明了这一点。后一组在上述方面表现出几乎正常的结果。因此，超声检查方法被证明对心内膜弹力纤维增生症病例的诊断和临床状况评估非常有用。
