Abstract

A patient who developed a subvalvular left ventricular pseudoaneurysm following mitral valve replacement is presented, the fourth such case in the literature. The etiology of this uncommon complication is felt to be caused by excessive surgical resection of the diseased mitral valve, which may weaken or cause rupture of the heart at the mitral annulus. The diagnosis can only be made by left ventriculography. Surgical treatment is indicated, because rupture of the pseudoaneurysm can occur.

摘要

本文报告了一例二尖瓣置换术后发生左心室瓣下假性动脉瘤的患者，这是文献报道的第四例此类病例。这种罕见并发症的病因被认为是由于对病变二尖瓣进行了过度手术切除，这可能会削弱二尖瓣环处的心脏组织或导致心脏破裂。只有通过左心室造影才能做出诊断。由于假性动脉瘤可能破裂，因此需要进行手术治疗。
