What is ​Congenitally Corrected Transposition of the Great Arteries (CCTGA)?

Also known as: CCTGA, corrected transposition of the great arteries

In a normal heart the left ventricle (the stronger pumping chamber) sends blood through the aorta to the rest of the body. The right sided pumping chamber (the right ventricle) pumps blood to the lungs. In Congenitally corrected transposition of the great arteries is a birth defect that impacts the heart. Specifically, the two lower chambers of the heart, the ventricles, are reversed in position, so the weaker right ventricle is on the left pumping blood to the body and the stronger left ventricle pumps blood to the lungs. The valves that allow blood to flow between heart chambers are also reversed.
