Transposition of the Great Arteries
Diagnosis
A complete transposition usually is diagnosed shortly after birth due to the baby's increasing blue coloration or cyanosis. There may or may not be a heart murmur or extra sound in the heartbeat.
Tests may include:
- Oxygen saturation test to check the level of oxygen in the blood Electrocardiogram (EKG or ECG), which records the heart's electrical activity
- Chest X-ray to see the heart's size
- Echocardiogram, which is an ultrasound examination of the heart
In addition, a cardiac catheterization procedure may be used to inject a dye into the heart and to see on a moving picture X-ray how the heart is functioning.
