Congenital Coronary Aneurysm: Unusual Presentation of Myocardial Ischemia in Children.

Coronary artery aneurysms in children are usually associated with inflammatory disease such as Kawasaki disease or connective tissue disease. Congenital coronary aneurysm is a rare entity with few case reports published in the literature. We report an unusual case of congenital coronary aneurysm in an 11-year-old boy presented to our center with an ischemic cardiac event. Further investigations including computed tomography scan, cardiac magnetic resonance imaging, and coronary angiography revealed a large aneurysm arising from the proximal segment of left anterior descending (LAD) artery. Surgical repair was done including aneurysm resection and roofing the LAD artery using autologous saphenous vein patch.
