Percutaneous coronary intervention strategies for patients with coronary artery ectasia and ST-segment elevation myocardial infarction: A report of two cases.

Abstract

Coronary artery ectasia （CAE） is characterized by dilated coronary arteries more than 1.5 times in diameter than normal coronary arteries. It has been reported that CAE is present in 1-5% of patients undergoing coronary angiography and is more common in males. CAE can be caused by Marfan syndrome, Kawasaki disease, and atherosclerotic alterations with expansive arterial remodeling of the tunica media of the coronary artery as the most common cause. Although acute myocardial infarction has been reported to occur in 40-60% of patients with CAE, the therapeutic strategy to manage myocardial infarction caused by excessive thrombus remains unclear. Here, we report two challenging cases of acute myocardial infarction with CAE undergoing primary percutaneous coronary intervention.
