Ruptured mycotic pseudoaneurysm of the thoracic aorta.

A 68-year-old man being treated for a Staphylococcus aureus bacteremia developed hemoptysis. A transesophageal echocardiogram (TEE) and computed tomographic (CT) scan showed a large descending thoracic aorta pseudoaneurysm. The patient died before surgical intervention could be performed.

Thrombus of the ascending aorta: a rare cause of myocardial infarction.

We present two cases of a thrombus in the ascending aorta causing an acute myocardial infarction (AMI) and review the 10 other cases previously reported in the literature. This life-threatening condition appears to be more common in female smokers in their fifth decade. Suspicion should be raised in individuals at low risk for atherosclerotic disease with coronary angiographic findings not in keeping with the clinical presentation.
