Transposition of the Great Arteries

Transposition of the Great Arteries (TGA) is a congenital heart defect where the two main arteries leaving the heart—the aorta and pulmonary artery—are switched. This means that oxygen-poor blood is sent back to the body instead of going to the lungs, while oxygen-rich blood returns to the lungs instead of circulating through the body. This condition can cause serious health issues, as the body does not receive the oxygen it needs. Treatment typically involves surgery to correct the arterial positioning, allowing for proper blood flow and oxygenation. Timely intervention is crucial for a positive outcome.
