Giant right coronary artery aneurysm in an adult male patient with non-ST myocardial infarction.

The combination of a giant coronary aneurysm with multiple coronary aneurysms in adults is an extremely rare entity--especially in atherosclerotic patients, since it is most commonly associated with Kawasaki disease in children. We report an interesting case of a 59-year-old male patient with multiple atherosclerotic aneurysms of the left coronary system and a giant aneurysm of the right coronary artery. The patient was admitted to our hospital because of a non-ST myocardial infarction. Diagnosis was established by echocardiography, computed tomography angiogram, and coronary angiography. In view of the clinical symptoms and the extent of the giant right coronary aneurysm, with the associated risk of rupture, the patient was successfully treated with urgent surgical intervention. We also present a review of the current literature on this anomaly and a statistical analysis of all atherosclerotic giant coronary artery aneurysms previously reported.
