The patients recovered uneventfully from operation. It results in low oxygenation of blood due to the mixing of oxygenated and deoxygenated blood in the left ventricle via the ventricular septal defect, and preferential flow of the mixed blood through the overriding aorta because of the obstruction of the pulmonary stenosis.
