TGA means the aorta and pulmonary arteries in the heart are switched. When a child is born with TGA there is very little oxygen in the blood. The aorta receives the oxygen-poor blood from the right ventricle, but it's carried back to the body without receiving more oxygen. The pulmonary artery receives the oxygen-rich blood from the left ventricle but carries it back to the lungs.
