What is Transposition of the Great Arteries (TGA)?

Also known as: TGA, blue-baby syndrome

Transposition of the great arteries, also called blue-baby syndrome, is a heart condition that is present at birth due to abnormal development of the fetal heart during pregnancy, in which the two major arteries that carry blood from the heart to the lungs and the body are wrongly connected. TGA is the second most common congenital heart defect in newborns.
