A patient is described in whom an aneurysm of the posterior mitral leaflet caused severe mitral incompetence and cardiac failure. The aneurysm was seen as an additional echo-free space within the left atrium in the real time two dimensional echocardiogram. Both echocardiographic and cineangiocardiographic appearances were misinterpreted initially because the aneurysmal leaflet did not more into the left ventricle during diastole. This feature was explained during the successful surgical repair of the valve by the observation that the aneurysm was adherent to the left atrial wall.
本文描述了一名患者，其二尖瓣后叶动脉瘤导致严重二尖瓣反流和心力衰竭。在实时二维超声心动图中，动脉瘤表现为左心房内额外的无回声区。最初，超声心动图和心血管造影表现均被误判，因为舒张期动脉瘤瓣叶未进入左心室。在瓣膜成功手术修复过程中发现，动脉瘤附着于左心房壁，从而解释了这一特征。
