What is ​Double Outlet Right Ventricle (DORV)?

Also known as: DORV

If a fetus’s heart forms improperly in the womb, double outlet right ventricle, or DORV, is one of the many congenital heart defects that can occur. Specifically, double outlet right ventricle means that both the aorta and the pulmonary artery, the body’s two main arteries, come out of the right ventricle. Ordinarily, the aorta comes out of the left ventricle. Most children born with DORV also have a hole in the wall of the septum that separates the right ventricle from the left ventricle.
