Transposition of the Great Arteries (TGA)

Transposition of the great arteries (TGA) is a rare but serious congenital (present at birth) heart defect where the two main arteries leaving a baby’s heart are in the wrong position. All babies with TGA will need heart surgery soon after they’re born. At Nemours Children's Cardiac Center, we offer leading-edge capabilities to detect heart problems early using fetal cardiac diagnostics. Our board-certified, fellowship-trained pediatric cardiologists and cardiothoracic surgeons (specialists in surgical procedures of the chest, including the heart and lungs) are here to answer your questions, address your concerns, and help with treatment plans. Our cardiac teams offer the latest in research-backed care, delivered with compassion.
