Symptoms of Tricuspid Atresia

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

Symptoms of tricuspid atresia may include:

  • Murmur (the sound of blood moving in the heart)
  • Bluish skin tone (cyanosis)
  • Fast breathing (tachypnea)
  • Working hard to breathe
  • Poor feeding
  • Poor weight gain or growth

Tricuspid Atresia Diagnosis

To diagnose this condition, your doctor will examine your baby and use a stethoscope to listen to their heart. 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, an ultrasound of the heart, test so the doctor can see how their heart works.

Your child may need other tests. These will likely include:

  • Chest X-rays
  • Blood tests
  • Electrocardiogram
  • Cardiac catheterization
