The most significant complication of tricuspid atresia is a lack of oxygen to your baby's tissues (hypoxemia). This can be life-threatening.

Complications later in life

Although treatment greatly improves the outcome for babies with tricuspid atresia, they may still have complications later in life, even after surgery, which may include:

  • Formation of blood clots that may lead to a clot blocking an artery in the lungs (pulmonary embolism) or to a stroke
  • Easily tiring when participating in sports or other exercise
  • Heart rhythm abnormalities (arrhythmias)
  • Certain complications in the lymphatic system
