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.
