摘要

本文报告了4例二尖瓣返流的病因及超声心动图的表现。外科医生在手术中确定了脊索的冗余。实验结果如下:1.实验结果表明:脊索多余的病因要么是先天性的,风湿病,或粘液变性。2. 这种情况的心音图表现为全收缩期杂音伴舒张期心尖隆隆声。3.二维超声心动图显示二尖瓣小叶的全收缩期膨大,多余的脊索附着在小叶上。4. m型超声心动图表现为多重线性回声和收缩期二尖瓣弯曲。

[Mitral regurgitation due to redundant chordae].

This paper reports the etiology and the findings of phonocardiograms and echocardiograms in four cases with mitral regurgitation caused by the redundant chordae. Redundancy of the chordae were determined by the surgeon during operation. The results were as follows: 1. The etiology of redundant chordae was either congenital, rheumatic, or mucoid degeneration. 2. Phonocardiographic findings of this condition are a holosystolic murmur accompanied by a diastolic rumble at the apex. 3. Two-dimensional echocardiogram shows holosystolic bulging of the mitral leaflet to which redundant chordae are attached. 4. The findings of the M-mode echocardiogram are multiple linear echoes and bowing of the mitral valve in systole.
