      • Pathology

        • Clinical Issues

          TERMINOLOGY

          • Abbreviations

            • Double outlet right ventricle (DORV)
          • Definitions

            • Form of abnormal ventriculoarterial connection in which both great arteries arise completely or predominately from morphologic right ventricle
            • 16 variants based on relationship of great arteries & position/location of ventricular septal defect (VSD)
            • Fibrinous discontinuity between mitral & semilunar valves or bilateral conus
            • May be part of complex lesions coexisting with ventricular anomalies, valve stenosis or atresia, abnormal atrioventricular valve, aortic valve anomalies, coarctation, coronary anomalies, & anomalies of systemic & pulmonary venous return
            • Taussig-Bing anomaly with DORV is subpulmonary VSD where left ventricular outflow is directed toward pulmonary artery with preferential flow
