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破裂并在左心室和左心房之间形成瘘管交通。这种情况下肺静脉收缩期血流逆转反映了由于分流导致的左心房压力升高。这一发现，尤其是在心内膜炎背景下，并非严重二尖瓣反流所特有。
