摘　　要：目的 探讨二尖瓣瓣膜瘤(MVA)的临床特点和超声心动图表现。方法 回顾性分析5例经胸超声心动图诊断的MVA患者。结果 5例均为亚急性感染性心内膜炎导致的主动脉瓣赘生物及穿孔,MVA均位于前叶,其中4例瘤体均≤10 mm,仅1例瘤体>10 mm。5例均有中度或重度二尖瓣反流。结论 MVA多为感染性心内膜炎累及主动脉瓣的并发症之一,经胸超声心动图可准确诊断MVA。Objective To investigate the clinical and echocardiographic features of mitral valve aneurysm(MVA).Methods Five patients with MVA diagnosed by transthoracic echocardiography in our hospital were analyzed retrospectively.Results All 5 cases had aortic valve vegetations and perforation caused by subacute infective endocarditis,and the MVA was located in the anterior mitral valve leaflet.The diameter of MVA was less than or equal to 10 mm in 4 cases and larger than 10 mm in 1 case.All 5 cases had moderate or severe mitral regurgitation.Conclusions MVA is one of the complications of infective endocarditis involving the aortic valve.Transthoracic echocardiography can accurately diagnose MVA.
