Stenotic double‐orifice mitral valve after surgical repaired partial atrioventricular septal defect

Double‐orifice mitral valve (DOMV) is an uncommon congenital anomaly account for 1% of congenital heart disease. However, accurate diagnosis and evaluation of valve stenosis or regurgitation and other concomitant congenital anomalies due to DOMV are required to obtain suitable treatment. Two‐ and three‐dimensional echocardiography can contribute valuable functional and anatomic information that can support to reach this goal. Here, we present a case of complete bridge‐type DOMV that causes mitral stenosis after surgical repair of the partial atrioventricular septal defect in childhood.
