Which of the following is the treatment of choice for the neonate with transposition of the great arteries?

Surgery: Within a baby’s first two weeks, transposition of the great arteries is surgically repaired through a procedure called an “arterial switch.” While supported by a heart-lung machine, the aorta and pulmonary arteries are disconnected, then “switched” and reconnected to their proper ventricles.

How long does arterial switch procedure take?

The surgery to repair TGA is known as an arterial switch operation. A pediatric heart surgeon performs the surgery. The surgery lasts about 4 to 6 hours. It takes place in an operating room in a hospital.

Is TGA genetic?

What causes TGA? There is no known cause of TGA. Some patients with TGA have genetic disorders. TGA does not run in families, but there is an increased chance of having a congenital heart defect if a relative also was born with a heart defect.

Is transposition of the great arteries fatal?

Transposition of the great arteries or TGA is a potentially fatal congenital heart malformation where the pulmonary artery and the aorta are switched. The switch means that the aorta, which normally carries oxygenated blood, carries deoxygenated blood.

Can TGA be detected before birth?

TGA is sometimes diagnosed by fetal ultrasound before the baby is born. First trimester screening for chromosomal abnormalities is a good screening tool to identify patients who might be at an increased risk for cardiac defects.

How common is TGA in newborns?

Occurrence. The Centers for Disease Control and Prevention (CDC) estimates that about 1,153 babies are born with TGA each year in the United States. This means that every 1 in 3,413 babies born in the US is affected by this defect.

Why is transposition of the great arteries fatal?

What causes baby TGA?
