In transposition of the great arteries, the main vessel that connects the heart to the body (the aorta) is connected incorrectly so that less oxygenated (“blue”) blood goes out to the body instead of to the lungs to pick up more oxygen. The main vessel that connects the heart to the lungs (the pulmonary artery) is connected so that more oxygenated (“red”) blood from the lungs goes back to the lungs without going to the body. Without surgical correction of transposition of the great arteries, a child with this defect does not live long. As a result of the artery mix-up, the body is starved of oxygen, which can cause death.
