What are the symptoms of pulmonary atresia?

Symptoms of pulmonary atresia are noticeable shortly after a baby’s birth. The most obvious symptom is a bluish tint to the skin, called cyanosis. Other common symptoms include:

  • extreme tiredness
  • pale, cool or clammy skin
  • breathing problems
  • feeding problems

If your baby’s pediatrician notices any of these symptoms, he or she will order testing right away.

What causes pulmonary atresia?

There is no clear cause for this condition. When a baby has pulmonary atresia, the pulmonary valve simply doesn’t develop properly during the first weeks of heart development.

In some cases, congenital heart defects may have a genetic link, either due to a defect in a gene or a chromosome abnormality — causing heart problems to occur more often in certain families.
