In a normal heart, the pulmonary artery carries deoxygenated blood to the lungs. Oxygenated blood returns to the left side of the heart and the aorta then pumps the oxygenated blood to the rest of the body. In Transposition of the Great Arteries (TGA), the pulmonary artery and aorta have changed places (i.e., they are transposed). Therefore:
The pulmonary artery, which usually arises from the right side of the heart and carries deoxygenated blood to the lungs, will now connect to the left side of the heart and send oxygenated blood back to the lungs
The aorta, which usually arises from the left (oxygenated) side of the heart, is now exiting the right side and therefore will carry deoxygenated blood to the rest of the body, bypassing the lungs
5 out of 10,000 babies are born with TGA
TGA is referred to as a ‘cyanotic’ (lacking oxygen) defect leading to babies with bluish discoloration and shortness of breath, with symptoms dependent on whether there is any ability for the deoxygenated and oxygenated blood to mix and be delivered to the rest of the body
Surgery is often necessary shortly after birth, especially in the case of complete TGA (also known as d-TGA referring to ‘dextroposition’) which is considered a ‘critical congenital heart defect’

While TGA can be diagnosed prenatally on ultrasound, it may not always be detected
In the majority of cases, a cause is not readily apparent
In some cases, TGA can be associated with genetic abnormalities and therefore, if a prenatal diagnosis is made or suspected, referral for genetic counseling is recommended, in addition to high risk obstetrical services, neonatology and pediatric cardiology
TGA is sometimes referred to as Transposition of the Great Vessels (TGV)
