[Embolism of the anterior descending artery as a cause of myocardial infarct in a patient with a prosthetic aortic valve].

A patient aged 42 with the aortic valve prosthesis was examined with the help of coronography and ultrasonic scanning of the heart in the period of ischemic injury of the anterior myocardium: occlusion of the unchanged anterior descending artery by an embolus formed on the artificial cardiac valve was revealed. Despite rapid recovery of arterial permeability (3 h 47 min, after the onset of disease) by intracoronary administration of streptase with subsequent anticoagulant and antiplatelet drug therapy the patient developed anterior myocardial infarction with left ventricular aneurysm and intracardiac thrombosis.
