Coronary artery aneurysm is an uncommon occurrence, yet it is described more often today than in the past as coronary angiography is now routinely used for diagnosis and treatment of ischemic heart disease. However, there is no therapeutic consensus regarding this finding. We present a case of giant coronary artery aneurysm and review the literature on the use of polytetrafluoroethylene-covered stents as a therapeutic option for this condition. Combined antiaggregant therapy is needed after the procedure. Randomized controlled trials of surgery versus covered stents are necessary to define the best treatment for large coronary artery aneurysms.
