A 70-year-old man with a diastolic Levine V/VI musical murmur came to our department. Doppler color-flow imaging showed eccentric severe aortic regurgitation. M-mode echocardiography demonstrated fluttering of the anterior mitral leaflet and fine tremors at the aortic root. The curved M-mode representation of the myocardial strain rate showed that the basal septum was encoded in a mixture of blue and red spots during diastole, showing massive basal septal vibration. In the present case, the force of the regurgitant flow might have caused vibration of the basal septum, thereby possibly leading to distinct thrill.
一名70岁男性，出现舒张期Levine V/VI级音乐样杂音，前来我院就诊。多普勒彩色血流成像显示偏心性重度主动脉瓣反流。M型超声心动图显示二尖瓣前叶扑动及主动脉根部细微震颤。心肌应变率的曲线M型表现显示，舒张期基底室间隔编码为蓝色和红色斑点的混合，提示基底室间隔大量振动。在本病例中，反流血流的力量可能导致基底室间隔振动，从而可能导致明显的震颤。
