[Fistula-producing giant coronary aneurysm in a 62-year-old woman].

Giant coronary aneurysms (GCA with a diameter > 20 mm) are rare with a prevalence < 0.02%. A 62-year-old woman with no history of ischaemic heart disease was admitted to hospital with acute chest pain. A coronary angiography revealed a left an-terior descendent-associated GCA. A cardiac computed tomo-g-raphy demonstrated a "snake-pit"-like fistula connecting the GCA and the pulmonary artery. Atherosclerosis, connective tissue dis-orders, and previous coronary intervention will predispose to GCA. No evidence-based treatment regimen exists, but coiling, excision or a conservative approach, as in this case, is possible strategies.
