Abstract:
A case of acute myocardial infarction (AMI) due to thrombus in the left coronary cusp to the ascending aorta is described. There was no clinical evidence of coagulopathy, immunodisability, or local erosive lesion of the aortic and sinus of Valsalva wall macroscopically. Secondary polycythemia, induced by heavy smoking, was the likely cause of the myocardial infarction. Although this may be a rare case, intraaortic thrombus should be considered in the differential diagnosis of the causes of AMI.
