Congenital Heart Defects
Exams and Tests
Several tests can be used to help determine whether a baby or child has a congenital heart disease. These may include:
Fetal echocardiogram (during pregnancy): This test shows moving pictures of a baby’s heart and how it is working as early as 16-18 weeks into pregnancy. It is usually used if congenital heart disease runs in your family, or if there are other factors that make a heart problem more likely.
Pulse oximetry: This simple and painless test measures how much oxygen is in the baby’s blood. In many states, it is a standard screening test for newborns to help detect possible problems.
After a full physical exam and if a heart issue is suspected, other tests may be ordered for the baby or child and may include:
- Chest X-ray
- Cardiac catheterization
- Cardiac stress test
A pediatric or fetal cardiologist is in the best position to diagnose a congenital heart defect and recommend treatment.
