Double Outlet Right Ventricle

Full Definition

Double outlet right ventricle (DORV) is a complex congenital heart malformation characterized by both great vessels (aorta and pulmonary artery) originating from the right ventricle, with the left ventricle typically connected to the great vessels only through a ventricular septal defect. This condition represents a spectrum of anatomic variations and is often associated with other cardiac anomalies. The clinical presentation and surgical approach depend on the relationship between the great vessels, the location and size of the VSD, and the presence of pulmonary stenosis. Treatment typically requires complex surgical reconstruction to establish normal blood flow patterns.

Usage

Usage note: Often abbreviated as DORV. Ensure accurate description of associated anatomical features in surgical planning documents.
