At the UPMC Children’s Heart Institute, we provide the most advanced treatment for complex congenital heart defects. New or expecting parents whose baby is diagnosed with transposition of the great arteries (TGA) have access to a multidisciplinary team of experts providing the full scope of care. From innovative treatments to ongoing support for patients and their families, our team cares for patients at every stage.
TGA is a group of congenital heart defects, meaning the condition is present at birth. These defects occur when the two main blood vessels leaving the heart are reversed. In typical TGA, the aorta is connected to the right ventricle, and the pulmonary artery is connected to the left ventricle. This reduces the amount of oxygen-rich blood sent to the body. Babies born with TGA can have additional differences in their hearts, such as:
- Differences in the valves of their hearts.
- Septal defects.
- Holes in the walls separating the main chambers of the heart.
Babies with TGA can require different treatment plans depending on these additional differences.
There are two main types of TGA:
- Dextro-transposition (D-TGA). This is the most common form of TGA. It’s diagnosed during pregnancy or soon after birth. D-TGA typically requires surgical repair within the first year.
- Levo-transposition (L-TGA). L-TGA, also referred to as congenitally corrected TGA, is less common.This condition may be identified during pregnancy or infancy, although in some people, symptoms are not noticed until later in life.
Through advanced 3D cardiac imaging, our experts see detailed information about the structure and function of the heart. This enhances our team’s view of the condition and can improve our surgical approach. Our team can also use 3D imaging after surgery to assess the heart and the success of the surgery.
