A rare congenital defect, TAPVR causes the four pulmonary veins to connect and drain into the right atrium of the heart instead of the left atrium of the heart. It is most commonly diagnosed soon after birth, though in mild cases a child may show signs later in life. Symptoms Newborns with TAPVR are very ill from birth and may have blue skin (cyanosis). Older children will show signs of a heart murmur. Treatment Surgery is needed to correct the defect.
