How is transposition of the great arteries diagnosed?

If, during pregnancy, a routine prenatal ultrasound or other signs raise suspicion of a congenital heart defect in the fetus, a cardiac ultrasound of the baby in utero will usually be the next step. The cardiac ultrasound can usually detect transposition of the great arteries (TGA).

If your newborn baby was born with a bluish tint to his skin, or if your child is experiencing certain symptoms, your pediatrician will immediately refer you to a pediatric cardiologist, who will perform a physical exam. Your child’s doctor will listen to your baby’s heart and lungs, measure the oxygen level in his blood (non-invasively) and make other observations that help to determine the diagnosis.

For most patients, a echocardiogram (cardiac ultrasound) and chest x-ray is all that’s needed to form a diagnosis. But in certain circumstances, other tests may be necessary:
