Congenitally corrected transposition of the great arteries (CCTGA) is a rare heart defect in which the heart’s lower half is reversed. It is also called L-TGA. It is different from and much less common than “regular” transposition of the great arteries (TGA or D-TGA). To understand CCTGA, it helps to first understand how a normal heart works. A normal heart is divided into two sides. The right side pumps blood from the body into the lungs. The left side pumps the blood from the lungs out to the body. Each side has an atrium and a ventricle. The atrium acts like a “waiting room” for the blood. The ventricle does the hard work of pushing the blood out to the lungs or body. At the entrance and exit from each ventricle is a valve, which acts like a door. These valves allow the ventricle to fill with blood from one side, and then push it out the other. Each ventricle and valve is designed to do its specific job. The right ventricle is designed to give the blood a gentle push to send it to the lungs. It is bigger than the left ventricle and does not have as much muscle. The left ventricle is designed to give the blood a strong push out to the body. It has less space inside because its thick walls take up more space. The valve between the left atrium and ventricle, the mitral valve, is the body’s strongest valve. It is designed to stay shut against the strong push of the blood out to the body. In CCTGA, the two ventricles and their attached valves are reversed. Your weaker, larger right ventricle grows on your heart’s left side. It pumps your blood to your body. Your stronger, smaller left ventricle grows on your heart’s right side. It pumps blood to the lungs. You also have your body’s weakest valve—the tricuspid
