(Pulmonary Stenosis—Child)



Symptoms may include:
  • Heavy or rapid breathing
  • Shortness of breath
  • Blue or pale grayish skin color
  • Fatigue
  • Rapid heart rate
  • Swelling of the feet, ankles, eyelids, and abdomen
  • Urinating less
Your doctor may also detect a heart murmur in your child during a physical exam.
These symptoms may be caused by other severe conditions. If your child has any of these, talk to the doctor right away.


If your child has mild pulmonary valve stenosis, immediate treatment may not be needed. Your doctor will monitor your child's condition to look for potential problems. Other treatment options include:


Your child may need surgery to prevent heart damage. Common types of heart valve surgery include:
  • Balloon valvuloplasty —A balloon is inflated in the valve to stretch out the surrounding tissue. This may provide temporary relief of symptoms but the valve may become blocked again.
  • Open heart surgery—to repair valves that can not be opened with balloon valvuloplasty.
  • Valve replacement—the valve is replaced with a mechanical or tissue valve

Complication Management

There are several steps your child can take to avoid some of the complications of pulmonary valve stenosis:
  • Get regular medical care. This includes basic checkups and heart tests.
  • Take antibiotics before any dental cleaning, dental work, or other invasive procedures if it is recommended by your doctor. Not all patients with valve stenosis need antibiotics for these procedures.
  • Eat a healthy diet that is low in salt. Work with the doctor or dietician to plan a healthy diet for your child. This may help decrease the pressure in your child’s heart and improve symptoms.
  • Monitor blood pressure at home. Inform the doctor if your child seems to be developing high blood pressure .


Ways to prevent heart defects are not entirely clear and may not always be possible. However, good prenatal care may reduce your risk of having a child with a heart defect. During pregnancy:
