Tetrology of Fallot


Prevention & Expectations

What can be done to prevent the condition?

Many times nothing can be done to prevent the disease. However, it may help if a pregnant woman avoids certain factors known to put a fetus at higher risk for this disease, such as alcohol.

What are the long-term effects of the condition?

Unless the child's heart can be surgically repaired, tetralogy of Fallot is fatal. Treatment may be affected by complications, such as the following:

  • an infection of the inner lining of the heart called infective endocarditis
  • further damage to the pulmonary valve
  • blood clots
  • stroke
  • development of an abscess, or pus-filled cavity, in the brain
  • What are the risks to others?

    Tetralogy of Fallot is not contagious, and poses no risks to others.
