Don't mean to step on toes, but you actually only speak of two, maybe three (it's vague, so I'm not sure) of the aspects of TOF. Tetralogy means four, so there are four parts to this defect. My daughter has TOF with PA.
Tetralogy of Fallot / TOF is a cardiac anomaly that refers to a combination of four related heart defects that commonly occur together. The four defects include:

1. Pulmonary stenosis (narrowing of the pulmonary valve and outflow tract or area below the valve, that creates an obstruction (blockage) of blood flow from the right ventricle to the pulmonary artery
2. Ventricular septal defect / VSD
3. Overriding aorta (the aortic valve is enlarged and appears to arise from both the left and right ventricles instead of the left ventricle as occurs in normal hearts)
4. Right ventricular hypertrophy (thickening of the muscular walls of the right ventricle, which occurs because the right ventricle is pumping at high pressure)[/b]

and... may I ask your source? Because it worries me that it says, "sometimes" further operation is required. Very very often, it requires further surgery.
