RODRIGUEZ, Julio C; RIVERA, Alex  e  PINZON, Bibiana. Aneurysm of the main trunk of the left coronary artery: Description of a clinical case and literature review. Rev. Colom. Cardiol. [online]. 2010, vol.17, n.3, pp.130-140. ISSN 0120-5633.

Coronary artery aneurysm is a rare entity in the population. Its incidence rates vary between 1.5% - 5%, and is more frequent in males. There is limited literature on this disease, although its study goes back to the late eighteenth century. The most frequently affected artery is the right coronary artery, in approximately 40% of cases. The initial diagnostic difficulty lies in the fact that the initial approach is focused in confirming and treating properly the coronary acute syndrome, which is the most frequent initial presentation in these patients. Therefore, its diagnosis requires necessarily imaging or interventionist aid, or both. Many causes account for coronary aneurysms, being the most common atherosclerosis followed by congenital abnormalities, connective tissue diseases, vasculitis and cocaine consumption. Novel studies regarding the physiopathology and advances in pharmacological and interventionist therapy have been published, although treatment must focus on risk factors, associated pathologies and clinical manifestations.
