Coronary artery aneurysms: Comprehensive review and a case report of a left main coronary artery aneurysm.

Coronary artery aneurysms (CAAs) are rare anatomical disorders of the coronary arteries. Atherosclerosis and Kawasaki disease are the principal causes of CCAs, while other causes including genetic factors, inflammatory arterial diseases, connective tissue disorders, endothelial damage after cocaine use, iatrogenic complications after interventions and infections, are also common among patients with CAAs. Although there is a variety of non-invasive methods including echocardiography, computed tomography, and magnetic resonance imaging, coronary angiography remains the gold standard diagnostic method. There is still no consensus about the most appropriate therapeutic strategy. Medical therapy including antiplatelets, anticoagulants, statins and ACEs are preferred either in patients with atherosclerosis, inflammatory status and stable CAAs, while percutaneous or surgery interventions are usually applied in patients with acute coronary syndrome due to a CAA culprit, obstructive coronary artery disease or large saccular aneurysms at a high risk of rupturing.
