Abstract
Coronary artery aneurysms (CAA) are a rare entity with an incidence of 0.3-5.3%. They are dilations of 1.5 times larger than normal adjacent artery, with the right coronary artery as the most affected vessel. Its pathophysiology is unclear but atherosclerosis is believed to be the main cause. CAA are generally asymptomatic but can cause coronary ischemia. Its treatment is yet to be established due to general ignorance about its nature. It ranges from conservative management to surgery. In the following text, we report a case of a patient with acute myocardial infarction presenting ST-segment elevation, who showed a right coronary artery aneurysm in coronary angiography. The patient required thrombectomy, angioplasty and subsequent lifetime outpatient medical management.
