Double outlet right ventricle

Double outlet right ventricle (DORV) is a type of congenital heart disease. Normally, the pulmonary artery originates from the right ventricle and the aorta originates from the left ventricle. In DORV, due to abnormal heart development during the embryonic stage, both the aorta and pulmonary artery originate from the right ventricle, or one great artery and most of the other great artery originate from the right ventricle. The main symptoms of this condition include cyanosis, fatigue, shortness of breath, and edema.
