研究二尖瓣腱索破裂（RMCT）的彩色多普勒超声心动图特征。
Objective:To study the characteristics of the color Doppler echocardiography of ruptured mitral chordae tendineae (RMCT) and its etiology and pathology.
目的：探讨二尖瓣腱索断裂的彩超特征和病因病理改变。
Results The surfaces of the prolapsed mitral valves showed rough and accompanied with abnormal tendinous chordae , and their bodies projected into left atrium during systole.
结果收缩期脱垂的二尖瓣表面粗糙并向左房膨出，可伴有腱索异常。
The prolapsed mitral valves and their tendinous chordae were viewed. The ranges of valvular prolapse were measured.
