A case of 'primary' mitral valve prolapse is documented. The patient was admitted with right-sided hemiplegia of sudden onset, probably caused by a cerebral embolus from the mitral valve. He also had a painless transmural inferior myocardial infarction (MI) of indeterminate age which was diagnosed electro cardiographically and on left ventricular cine angiography. Since selective coronary arteriography delineated the absence of fixed obstructive atherosclerotic disease, and since coronary vasospasm could not be provoked with the ergonovine (ergometrine) maleate test, it is further postulated that a coronary embolus from the abnormal mitral valve apparatus was responsible for the painless MI. A percutaneous right ventricular endomyocardial biopsy specimen displayed findings not indicative of a 'cardiomyopathy'.
