We present the case of a young man with severe eccentric aortic regurgitation, obstructing mitral inflow and provoking an audible Austin Flint murmur at clinical examination. Two-dimensional color Doppler echocardiography depicts the remarkable mechanical interaction between aortic regurgitant jet and anterior mitral leaflet opening. Three-dimensional transesophageal echocardiography aids in understanding the geometric and hemodynamic consequences of the regurgitant jet and in the genesis of the Austin Flint murmur. This case accentuates the incremental value of three-dimensional echocardiography when evaluating valvular pathology, and offers more insight in the interaction between aortic regurgitant flow and mitral leaflet dynamics.
我们报告一例年轻男性患者，患有严重的偏心性主动脉瓣反流，阻碍二尖瓣血流，并在临床检查时引发可闻及的奥斯汀·弗林特杂音。二维彩色多普勒超声心动图显示了主动脉反流束与二尖瓣前叶开放之间显著的机械相互作用。三维经食管超声心动图有助于理解反流束的几何和血流动力学后果以及奥斯汀·弗林特杂音的产生机制。该病例突出了三维超声心动图在评估瓣膜病变时的附加价值，并为主动脉反流与二尖瓣叶动力学之间的相互作用提供了更多见解。
