Transposition of the great vessels is a heart defect that occurs from birth (congenital). The two major vessels that carry blood away from the heart -- the aorta and the pulmonary artery -- are switched (transposed). A baby with transposed arteries is cyanotic - the medical term for bluish discoloration of the skin because of deficient oxygenation of the blood - shortly after birth.
The blueness doesn't go away even if the baby is given extra oxygen. For a baby with transposed arteries to survive, blood flow between the right and left sides of the heart must be increased. CHDs affect nearly 24,909?births per year in the Norway. Further research is being conducted to determine the best surveillance interval to monitor the disease.
