Three-dimensional echocardiographic imaging of double-orifice mitral valve determining severe mitral stenosis: diagnosis and intraoperative aspect of a very rare clinical entity

Abstract

Double-orifice mitral valve (DOMV) is a very rare congenital malformation characterized by the presence of two anatomically independent orifices in the left atrioventricular (AV) valve area. The DOMV results from the abnormal fusion of the endocardial cushions with the persistence of the left part of the common AV canal. Usually, DOMV is associated …
