Double outlet right ventricle (DORV) is a rare cardiac birth defect where both great arteries (the pulmonary artery and the aorta) arise from the right ventricle. No great arteries are connected to the left ventricle (the chamber that normally pumps blood to the body).
Most DORV defects are found with additional heart defects which may include:
There are different types of double outlet ventricles based on the location of the ventricular septal defect and the position of the great arteries. Prenatal diagnosis is important as babies with DORV may have additional organ or chromosomal abnormalities, such as 22q11 deletion syndrome.
Depending on their stability, babies with DORV require heart surgery in the first few days to months of life to correct the heart defect.
