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. (Level of Difficulty: Intermediate.).

Keywords: AVT, aortoventricular tunnel; LTBP4, latent transforming growth factor-beta binding protein; LV, left ventricle; aortoventricular tunnel; bicuspid aortic valve; dilated ascending aorta; fetal echocardiography.
