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 show up 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 not enough oxygen in the blood in their arteries.

Pulmonary Atresia Diagnosis

Prenatal diagnosis

Pulmonary atresia can be diagnosed while your child is in the womb using a fetal echocardiogram (fetal echo). This is a special ultrasound that uses sound waves to see and make pictures of a baby’s heart during pregnancy. A pediatric heart doctor (cardiologist) who is trained in fetal congenital heart disease will look at the results from your fetal echo.

If your family has a history of congenital heart disease, or a routine prenatal ultrasound shows a problem, your doctor may have you get a fetal echo.

We provide accurate diagnosis, thoughtful counseling and pregnancy management support through our Prenatal Diagnosis and Treatment Program.

Diagnosis in newborns

To diagnose this condition after your child is born, the doctor will examine your baby 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-rays, cardiac catheterization, electrocardiogram and pulse oximetry.
