WebFeb 11, 2024 · The right ventricular outflow tract (RVOT) is that part of the heart that carries blood out of the right ventricle to the lungs. Problems with the RVOT (like pulmonary atresia and pulmonary valve stenosis) are common among children with congenital heart defects, and many corrective surgeries for congenital heart defects, and dilatation of the ... WebThe VSD is usually large and unrestrictive, and the direction and severity of shunting depend upon the degree of RVOT obstruction. The higher the obstruction to blood flow exiting the RV to the PA, the more blood which will be forced across the VSD. This in turn determines the degree of cyanosis and the age of presentation.
