Double Outlet Right Ventricle With a Not-Directly-Committed Ventricular Septal Defect

A B C Figure 1.Preoperative 3-dimensional models created from computed tomography data.(A) Anterior view of the blood pool model showing long bilateral infundibula (asterisks).(B) Posterior view of the blood pool model showing coarctation of the aorta with a hypoplastic aortic arch.(C) A hollow model with partial removal of the RV wall.The ventricular septal defect (red line) is relatively remote from the semilunar valves and is not directly committed to either the AV or the PV.The arrow points to the outlet septum.AV = aortic valve; IVC = inferior vena cava; LA = left atrium; LPA = left pulmonary artery; LV = left ventricle; MPA = main pulmonary artery; MV = mitral valve; PDA = patent ductus arteriosus; PV = pulmonary valve; RA = right atrium; RV = right ventricle; T = trachea; TV = tricuspid valve; VIF = ventriculo-infundibular fold.
