Congenital Saccular Aneurysms of the Aortic Ring

Abstract

Congenital saccular aneurysms arising in the area of the aortic ring are not common. They may be located deep in the aortic sinus, at the commissure of two adjacent cusps, or in the area involving the membranous portion of the interventricular septum. They may be found at any age. This report concerns a child 2 years of age with a relatively large saccular aneurysm of the aortic ring just at the site of the commissure between the right and noncoronary cusps of the aortic valve. Terminally, this anomaly was complicated by infection leading to vegetative and ulcerative endocarditis. Death was sudden and was apparently directly related to the complications of the deformity.
