The clinical diagnosis of mitral-valve prolapse was made in ten patients on the basis of a late systolic murmur with or without a click. In each case the echocardiogram confirmed the diagnosis. In five it was further confirmed by angiocardiography. The late systolic murmur, with or without click, accentuated after nitroglycerin, is characteristic for mitral-valve prolapse.
