Pulmonary Valve Stenosis Child
Pulmonary valve stenosis is a problem with a valve in the heart. They valve is thickened or can't open fully. The damaged valve can:
- Decrease the amount of blood that reaches the lungs. This can decrease the amount of blood that is available to pick up oxygen.
- Increase the amount of work on the right side of the heart to work.
- Cause blood to back up into the heart.
For some, it may be a mild condition. Others may have severe problems.

Factors that may increase the risk of pulmonary valve stenosis may include:
- Family history of congenital heart defect
- Certain chromosomal disorders
- Other heart defects
Factors of the mother that may increase the risk of pulmonary valve stenosis in a child include:
- Previous pregnancy with fetal heart abnormalities or miscarriage
- Infection with a virus during pregnancy
- Maternal smoking during pregnancy
Mild stenosis may not need treatment right away. Your child’s care team will monitor your child for any changes or problems.
Moderate or Severe Stenosis
More severe stenosis may need surgery. Surgery may repair or replace the bad valve. It can help to relieve symptoms and prevent heart damage. Common options include:
- Balloon valvuloplasty —A balloon will be passed to the valve and gently inflated. It will stretch the tissue around the valve. This may only provide temporary relief. The valve may become blocked again.
- Open heart surgery—To repair valves that cannot be opened with less invasive options.
- Valve replacement—The valve is replaced with a mechanical or tissue valve.
Some health habits can decrease the risk of complications. Steps include:
- Get regular medical care. This includes basic checkups and heart tests.
- Talk to your doctor and dentist about antibiotics before any dental procedures. It can help to prevent an infection of the valve. Not everyone with valve stenosis will need this step.
Follow a heart healthy lifestyle that includes:
- Heart healthy diet with plenty of fruits and vegetable and whole grains
- Aim for a health weight
- Regular physical activity—may need to limit to low intensity; check with the doctor
- Monitor blood pressure at home—let the doctor know if your child has high blood pressure readings
It is not always clear why heart defects happen. As a result, prevention steps are not clear.
Good prenatal care can reduce the risk of some heart defects. To reduce the risk for a fetus:
- Visit your care team throughout the pregnancy. Certain tests may show a heart defect in a growing fetus.
- Practice healthy habits during the pregnancy. This includes healthy eating and prenatal vitamins.
- Do not drink alcohol, smoke, or use drugs during pregnancy.
