What is Transposition of the Great Arteries (TGA)?
Transposition of the Great Arteries (TGA) is a serious congenital heart defect where the two main arteries leaving the heart are reversed. Specifically, the aorta arises from the right ventricle, and the pulmonary artery arises from the left ventricle. This anatomical anomaly results in poorly oxygenated blood circulating through the body, leading to severe complications if not corrected.
