Abstract

Pseudoaneurysms of the mitral-aortic intervalvular fibrosa can rupture and form fistulous communications between the left ventricle and left atrium. Pulmonary venous systolic flow reversal in such cases reflects elevated left atrial pressure due to shunting. This finding, particularly in the setting of endocarditis, is not specific for severe mitral regurgitation.

摘要

二尖瓣-主动脉瓣间纤维的假性动脉瘤可以破裂并在左心室和左心房之间形成瘘管连通。在这种情况下，肺静脉收缩期血流逆转反映了分流引起的左心房压力升高。这个发现,特别是在心内膜炎的背景下，对严重的二尖瓣反流没有特异性。
