Clinical and electrocardiographic evidence of transmural myocardial infarction developed in two patients (a woman, age 38, and a boy, age 17) with prolapsing mitral-leaflet syndrome. Both had normal coronary angiograms and normal plasma lipid levels. Left ventricular angiography showed dyskinetic areas in both patients. Coronary artery embolism or prolonged coronary artery spasm may have been the underlying mechanism of production of myocardial infarction.
