narrowing of the opening of the mitral valve: a result of chronic scarring that follows rheumatic fever. It may be seen alone or combined with mitral incompetence. The symptoms are similar to those of mitral incompetence except that the patient has a diastolic murmur. Mild cases need no treatment, but severe cases are treated surgically by reopening the stenosis (mitral valvotomy) or by inserting an artificial valve (mitral prosthesis).
