Tg pro right side3/31/2023 Your weaker, larger right ventricle grows on your heart’s left side. In CCTGA, the two ventricles and their attached valves are reversed. It is designed to stay shut against the strong push of the blood out to the body. The valve between the left atrium and ventricle, the mitral valve, is the body’s strongest valve. It has less space inside because its thick walls take up more space. The left ventricle is designed to give the blood a strong push out to the body, which is under higher pressure. It is bigger than the left ventricle and does not need to have as much muscle because it only requires a gentle push. The right ventricle is designed to push blood to the lungs, which are under low pressure. These valves allow the ventricle to fill with blood from one side, and then push it out the other so blood travels in one direction.Įach ventricle and valve is designed to push blood to the lungs, which are under low pressure. At the entrance and exit from each ventricle is a valve, which acts like a door. The ventricle does the hard work of pushing the blood out to the lungs or body. The atrium acts like a “waiting room” for the blood. Each side has an atrium, which is a chamber on the top, and a ventricle, which is a chamber at the bottom. The left side pumps the blood from the lungs out to the body. The right side pumps blood from the body into the lungs. To understand CCTGA, it helps to first understand how a normal heart works.Ī normal heart is divided into two sides. It is different from and much less common than “regular” transposition of the great arteries (TGA or D-TGA). *Please note: This article is directed to those who have not undergone a double-switch repair.Ĭongenitally corrected transposition of the great arteries (CCTGA) is a rare heart defect in which the heart’s lower half is reversed.
