Transposition of the Great Arteries

Transposition of the great arteries (TGA) is a rare but serious congenital heart defect, meaning it is present at birth, in which the two main arteries that leave the heart are reversed, or transposed. This changes the way blood circulates through the body, creating a shortage of oxygen in the blood that flows from the heart to the rest of the body. The body cannot function properly without an adequate supply of oxygen-rich blood. TGA usually is detected shortly after birth, and corrective surgery typically is required. The exact cause is not known. With proper treatment, most babies with TGA will grow up to lead healthy, productive lives, although they may require lifelong checkups with a cardiologist.

Why UAB

The UAB Congenital Heart Disease Program offers the most advanced care for structural heart disease, which often requires lifetime monitoring and care. Our multidisciplinary team of pediatric and adult cardiologists, cardiovascular surgeons, cardiovascular anesthesiologists, and maternal/fetal medicine specialists are uniquely qualified to treat patients before birth and into adulthood. In addition to seeing patients at the UAB Women & Infants Center and The Kirklin Clinic of UAB Hospital, UAB Medicine’s congenital heart disease specialists also see patients at North Alabama Children's Specialists in Huntsville and Physicians to Children/Central Alabama Children's Specialists in Montgomery.

Our modern ultrasound equipment allows many heart defects to be diagnosed before a child is born. Screening exams performed at 18-20 weeks are recommended for expectant mothers (or fathers) known to have congenital heart disease. If a defect is discovered, prenatal treatment and planning for delivery and postnatal treatment can be undertaken.

Thanks to advances in pediatric congenital care, the life expectancy for most patients now reaches far into adulthood, but more than 60% stop seeing a cardiologist once they turn 18. UAB’s Alabama Adult Congenital Heart Disease Program is designed to prevent that gap in care. As the only adult congenital heart disease program in the state and one of only a handful in the country, our expertise greatly increases the chances that symptoms will be identified early. This helps ensure that smaller problems are addressed before they develop into larger, more life-threatening issues such as heart failure, arrhythmia, residual congenital heart defects, endocarditis, and stroke.

Dr. Marc Cribbs appeared on Fox 6 TV's "Business Break" to discuss Adult Congenital Heart Disease.

More than 20,000 adults enter the Adult Congenital Heart Disease population every year, but 60% are lost to follow-up care.

Individuals born with congenital heart disease are now thriving into adulthood, but need lifelong follow-up care from sub-specialty experts.
