Pulmonary Valve Stenosis | Symptoms and Causes

What are the symptoms of pulmonary valve stenosis?

Children with mild to moderate pulmonary stenosis may not have any symptoms. Those with more severe severe pulmonary valve stenosis usually have symptoms shortly after birth, which may include:

  • cyanosis (bluish tinge to the skin)
  • lack of energy
  • pale, cool or clammy skin

In rare cases, older children can have symptoms that include:

  • feeling unable to exercise
  • heavy and rapid breathing
  • fatigue

What are the causes of pulmonary valve stenosis?

Pulmonary valve stenosis occurs due to improper development of the pulmonary valve in the first eight weeks of fetal growth. Most of the time, this heart defect occurs by chance, with no clear reason for its development.
