Pulmonary Atresia Symptoms and Diagnosis

Symptoms of Pulmonary Atresia

Most babies with pulmonary atresia show symptoms during the first few hours of life. However, in some babies, symptoms do not appear until a few days after birth.

If they do have symptoms, they may have these:

  • Bluish skin tone (cyanosis)
  • Fast breathing
  • Working hard to breathe
  • Tiring easily while feeding

The baby appears blue because there is less oxygen than there should be in the blood in their arteries.

Pulmonary Atresia Diagnosis

To diagnose this condition, your doctor will examine your child and use a stethoscope to listen to their heart. In children with this condition, doctors can often hear a heart murmur - the sound of blood moving in the heart in a way that's not normal.

The doctor will ask for details about any symptoms your child has, their health history and your family health history.

Your child will need an echocardiogram test so the doctor can see how their heart works.

Your child will probably need other tests as well. These include  chest X-rayscardiac catheterizationelectrocardiogram  and pulse oximetry.
