Congenital double-orifice mitral valve (DOMV) is a rare malformation that may affect both mitral valve and apparatus, and it is usually associated with other cardiac disorders. Asymptomatic DOMV is extremely rare. We present two similar cases of asymptomatic congenital double-orifice mitral valve. Both cases presented functionally normal mitral valve apparatus with two equally sized orifices, which were formed by a central fibrosis. In addition, final confirmatory diagnosis was made using three-dimensional (3D) echocardiography in both cases.
先天性双孔二尖瓣（DOMV）是一种罕见的畸形，可能影响二尖瓣及其附属结构，且通常与其他心脏疾病相关。无症状的DOMV极为罕见。我们报告两例相似的无症状先天性双孔二尖瓣病例。两例病例的二尖瓣附属结构功能均正常，有两个大小相等的孔，由中央纤维化形成。此外，两例病例均通过三维（3D）超声心动图进行了最终确诊。
