Giant Coronary Artery Aneurysm Imaging Findings Before and After Treatment With a Polytetrafluoroethylene-Covered Stent

Coronary artery aneurysm (CAA), defined as dilatation of the coronary artery exceeding 50% of the reference vessel diameter, is uncommon and occurs in 4 times or if they are >8 mm in diameter.2 Atherosclerosis accounts for the vast majority of CAAs in adults, whereas Kawasaki disease is responsible for most cases in children.1,2 Up to one third of CAAs are associated with obstructive coronary artery disease and have been associated with myocardial infarction, arrhythmias, or sudden cardiac death.3 A 63-year-old man with typical chest pain and a positive treadmill exercise test was referred for diagnostic coronary angiography.
