This report describes an unusual late complication of mitral valve replacement in which a false aneurysm of the atrioventricular groove produced compression on the circumflex coronary artery and myocardial infarction. The cause of this condition is not well explained, but its potential is present whenever there is early separation of the mitral anulus from the fibrous skeleton of the heart. Early hematoma formation resulting in frank perforation and hemorrhage has been reported, but late pseudoaneurysm formation after initial mitral valve replacement appears to be a rare occurrence.
本报告描述了二尖瓣置换术后一种不寻常的晚期并发症，即房室沟假性动脉瘤对回旋支冠状动脉产生压迫并导致心肌梗死。这种情况的病因尚不清楚，但只要二尖瓣瓣环与心脏纤维骨架过早分离，就存在这种可能性。已有报道早期血肿形成导致明显穿孔和出血，但二尖瓣置换术后晚期假性动脉瘤形成似乎很少见。
