Double‐orifice mitral valve associated with mild mitral stenosis and coarctation of the aortic isthmus: A rare case of incomplete form of Shone's syndrome

Shone's syndrome (SS) is a rare congenital cardiac anomaly characterized by a spectrum of developmental abnormalities. It predominantly presents as consisting of a variety of left ventricular inflow and outflow tract lesions, with inflow tract lesions typically including parachute mitral valve and supravalvular mitral ring. However, reports of SS involving double‐orifice mitral valve are scarce.
