Risk Factors

Factors that increase the risk for congenital heart defects like tricuspid atresia include:


Tricuspid atresia may be diagnosed before birth.
To confirm the diagnosis and determine the severity of the heart defects, your doctor may order imaging tests such as:



Medication may be given to:
  • Improve the levels of oxygen in the blood.
  • Manage the level of fluids in the body to decrease workload on the heart.
Oxygen may also be given to increase the amount of oxygen in the blood.


Surgery is often needed right away. Follow-up surgeries may also be needed at ages 3-6 months and 2-5 years.
The goal of surgery is to:
  • Improve blood flow within the heart
  • Restore connections between the heart, lungs, and body
The exact surgery will depend on the type and severity of defects that are present. For example, a shunt may be placed to increase blood flow to the lungs. Later a series of surgeries will be done to reroute blood flow through the heart, lungs and body.

Lifelong Monitoring

Your child will have regular exams from a heart specialist. Your child may also need antibiotics before certain medical or dental procedures to prevent a heart infection.
