• We describe three patients with supravalvular mitral stenosis caused by a diaphragm located just above the mitral valve and associated with a ventricular septal defect. Two of our three patients also had an associated coarctation of the aorta. The physical signs, ECGs, chest roentgenograms, and cardiac catheterization data are described. Points helpful in the differential diagnosis of this malformation are emphasized. All three patients were treated successfully by surgery.
