What Is Double Outlet Right Ventricle?

Double outlet right ventricle is a rare birth defect.

In double outlet right ventricle, both of the heart's "outlets" – the aorta and the pulmonary artery – exit from the right ventricle.

In a normal heart, the aorta leaves the left ventricle, carrying oxygen-rich (red) blood to the body, and the pulmonary artery leaves the right ventricle, carrying oxygen-poor (blue) blood to the lungs.

Many kinds of heart defects fall into the category of double outlet right ventricle. They all share the feature that the aorta and pulmonary artery both exit from the right ventricle; besides this, other parts of the heart may be different.

In double outlet right ventricle, there is almost always a hole in the septum, or wall, between the right and left ventricles called a ventricular septal defect. Some children also have a hole in the septum between the right and left atria called atrial septal defect or they have other defects, like pulmonary stenosis, aortic stenosiscoarctation of the aorta, mitral valve abnormalities or pulmonary atresia.

Double Outlet Right Ventricle in Children

This is a congenital defect. Doctors do not know why it happens. They think it occurs early in the pregnancy, when the baby’s heart is forming.

About one in every 10,000 babies has double outlet right ventricle.
