double outlet right ventricle

Full Definition

Double outlet right ventricle (DORV) is a complex congenital heart defect characterized by both the aorta and pulmonary artery arising predominantly or entirely from the right ventricle. The condition is classified based on the relationship of the ventricular septal defect to the great vessels, with subtypes including subaortic, subpulmonary, doubly committed, and remote VSD variants. Surgical management depends on the specific anatomy and may involve biventricular repair or single ventricle palliation.

Usage

Usage note: May be abbreviated as DORV in technical documents but should be spelled out in patient communications.
