Abstract
Aortoventricular tunnel is a rare congenital cardiovascular malformation whereby there is a paravalvular communication between the aorta and a ventricle. This unique case describes a newborn with an aortoventricular tunnel, a severely dilated ascending aorta, and a bicuspid aortic valve, which was suspected prenatally and surgically managed postnatally.
