Neonates with severe left ventricular outflow tract obstruction (LVOTO) may have a competent left ventricle and mitral valve allowing for biventricular repair (BVR), which can be performed as a primary complete neonatal repair or as a staged procedure. The Norwood procedure, which is characterized by a right ventricle to pulmonary artery (RV-PA) shunt, significantly reduced mortality in this operation. We present our experience with a 2-staged BVR in two neonates with severe LVOTO, in whom we employed the modified Norwood operation (RV-PA shunt) for initial management.
