What is tetralogy of Fallot repair?

Also known as: TOF repair, corrective repair of tetralogy of Fallot.

Tetralogy of Fallot (TOF) is a heart defect present at birth. TOF consists of four different heart abnormalities:

a ventricular septal defect (which is a hole between both ventricles in the heart)
overriding aorta (which is the major blood vessel in the heart that carries oxygenated blood to the body, lies on top of both ventricles instead of the left ventricle)
pulmonary stenosis (a narrowing around or at the pulmonary valve limiting the amount of blood that goes into the lungs)
right ventricular hypertrophy (right ventricle becomes thicker because of the increase amount of work has to perform in order to get the blood into the lungs).

TOF repair is a surgery that corrects these defects.
