Abstract

A 69-year-old woman with a mechanical aortic valve presented with decompensated heart failure. Emergent echocardiogram and fluoroscopy demonstrated acute aortic regurgitation due to a dysfunctional mechanical aortic valve and non-obstructive coronary disease. An emergent valve replacement was performed confirming a fixed-open valve with pathology demonstrating obstructive pannus formation without thrombosis or vegetation.

摘要

一名69岁的女性，患有机械主动脉瓣，患有失代偿性心力衰竭。紧急超声心动图和透视检查显示，由于机械主动脉瓣功能失调和非阻塞性冠状动脉疾病，导致急性主动脉瓣返流。进行了紧急瓣膜置换，确认了固定打开的瓣膜，其病理表明阻塞性血管nu形成而没有血栓形成或植被。
