The symptoms associated with Double Outlet Right Ventricle depend on the position of the Ventricular Septal Defect (VSD) and the degree of pulmonary valve stenosis (narrowing or obstruction of the valve opening). With at least moderate pulmonary stenosis, desaturated blood enters the aorta and cyanosis is present (right to left shunt). If an insufficient amount of blood is pumped to the lungs (because of significant pulmonary stenosis), the infant will have difficulty adding weight and may show blueness (cyanosis). On the other hand, if too much blood is pumped to the lungs, heart failure may result.
