Congenital mitral stenosis (MS) refers to the parachute deformity of the valve. In this condition, condensed chordae tendineae join and attach into a single large papillary muscle, usually with thickened leaflets of the mitral valve (MV), fusion of the chordae tendineae, accessory MV tissue, and supravalvular ring of the connective tissue rising at the base of the atrial aspect of the MV leaflets. Associated cardiac lesions are common and consist of coarctation of the aorta, patent ductus arteriosus, left ventricular outflow tract obstruction, and persistent left superior vena cava .
