Risk Factors

Factors that may increase the risk for congenital heart disease may include:


Low oxygen levels in the body may cause symptoms such as:
The doctor may also detect a fast heart rate during the exam.



Surgery is usually done right away, during infancy. The type of surgery depends on how severe the defect is. The goals are to improve circulation, which may be done by:
  • Creating a new pulmonary artery to carry blood to the lungs
  • Creating a new aorta to carry blood to the rest of the body
  • Closing the hole in the wall between the lower chambers of the heart
Other surgeries may be needed as your child grows.


Medications may be given to help support your child's heart before surgery. Medication may be given to:
  • Decrease fluid retention to lower workload on the heart
  • Improve heart function
After surgery, your child may need antibiotics before certain medical or dental procedures. This is to prevent an infection in the heart.

Lifelong Monitoring

Your child will have regular exams from a heart specialist.
