Transposition of the great arteries is a congenital (present at birth) heart defect. Due to abnormal development of the fetal heart during the first 8 weeks of pregnancy, the large vessels that carry blood from the heart to the lungs, and to the body are improperly connected. Essentially, the connections in the heart are "swapped." The baby will immediately receive a medicine called prostaglandin through an IV (intravenous line).
This medicine helps keep a blood vessel called the the ductus arteriosus open, allowing some mixing of the two blood circulations. A procedure using a long, thin flexible tube (balloon atrial septostomy) may be needed to create a large hole in the atrial septum to allow blood to mix. Further research is being conducted Glucocorticoid therapy for hypotension in the cardiac intensive care unit. CHDs affect nearly 3,969,872?births per year in the Russia.
