Tetralogy of Fallot is characterized by a large ventricular septal defect, an aorta that overrides the left and right ventricles, obstruction of the right ventricular outflow tract, and right ventricular hypertrophy. With substantial obstruction of the right ventricular outflow tract, blood is shunted through the ventricular septal defect from right to left (arrow).
