Transposition of the great arteries; TGA; d-TGA

The baby will immediately receive a medicine called prostaglandin through an IV (intravenous line). This medicine helps keep the ductus arteriosus open, allowing some mixing of the two blood circulations.

A procedure using cardiac catheterization (balloon atrial septostomy) may be needed to create a large hole in the atrial septum to allow blood to mix.

A surgery called an arterial switch procedure is used to permanently correct the problem within the baby's first week of life. This surgery switches the great arteries back to the normal position and keeps the coronary arteries attached to the aorta.

The child's symptoms will improve after surgery to correct the defect. Most infants who undergo arterial switch do not have symptoms after surgery and live normal lives. If corrective surgery is not performed, the life expectancy is months.

• Arrhythmias
• Coronary artery problems
• Heart valve problems

This condition can be diagnosed before birth using a fetal echocardiogram. If not, it is usually diagnosed soon after a baby is born.

Go to the emergency room or call the local emergency number (such as 911) if your baby's skin develops a bluish color, especially in the face or trunk.

Call your health care provider if your baby has this condition and new symptoms develop, get worse, or continue after treatment.
