Abstract:
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.
