Myxomas account for approximately half of all primary cardiac neoplasms. Most occur in the left atrium and only rarely are attached to the mitral valve, with just over 30 such cases reported in the literature. These neoplasms can manifest with a combination of obstruction of blood flow, systemic embolization, and constitutional symptoms.
We present a case of a 32-year-old African American man presenting at an emergency department with symptoms of a transient ischemic attack. Transesophageal echocardiography identified a mass originating from the posterior leaflet of the mitral valve. The mass was surgically resected and histologically classified as a myxoma. He remained asymptomatic during the course of 5-year surveillance.
Few similar cases have been described in the literature. Here we present a review of the diagnosis and surgical management of this rare presentation for mitral valve myxoma.
黏液瘤约占所有原发性心脏肿瘤的一半。大多数发生于左心房，极少附着于二尖瓣，文献报道仅有30多例此类病例。这些肿瘤可表现为血流梗阻、全身栓塞和全身症状的组合。
我们报告一例32岁非裔美国男性，因短暂性脑缺血发作症状就诊于急诊科。经食管超声心动图发现一个起源于二尖瓣后叶的肿块。该肿块经手术切除，组织学分类为黏液瘤。在5年的随访过程中，他一直无症状。
文献中很少描述类似病例。在此，我们对这种罕见的二尖瓣黏液瘤表现的诊断和手术治疗进行综述。
