Introduction:
Coronary artery aneurysm is a rare entity; with an incidence among patients undergoing coronary angiography that varies from 1.5-5% (1, 2). Although the exact definition of giant coronary artery aneurysm is lacking, however it is usually referred to as a dilated segment exceeding 4 times the diameter of the largest coronary artery or an aneurysm exceeding 8 mm in diameter (3)
Treatment options are percutaneous coronary angioplasty or surgery. Here, we present our operative approach in treating a giant aneurysm of the right coronary artery with double ligation and distal bypass grafting.
