Recurrent myocardial infarction caused by a giant coronary aneurysm

We report on a patient with a giant aneurysm arising from the right coronary artery leading to infarction due to a steal phenomenon. Emergency coronary angiography was performed. The orifice of the aneurysm was occluded by balloon catheter restoring blood flow and resolving ischemia. Aneurysmectomie was done subsequently. The patient recovered very soon, and the following course was uneventful. This case illustrates that occasionally causes other than usual coronary atherosclerosis may lead to acute coronary syndromes.
