A rare case of parachute mitral valve and dual drainage of the left upper pulmonary vein in a patient with Kabuki syndrome

A patient with Kabuki syndrome and a parachute mitral valve was referred for mitral stenosis. Echocardiography indicated right ventricular dilatation and a suspected vertical ascending vein. Cardiac CT confirmed dual drainage of the left upper pulmonary vein and hemiazygos vein continuity. Despite echocardiographic limitations, surgery was performed. This rare case is reported due to its unique anatomical variation.
