Heart surgery scar on the chest of a 3 month old baby. This is after stage 1 of a Norwood operation to correct hypoplastic left heart (HLH), a congenital malformation of the heart. In HLH, the left ventricle, the heart chamber that provides the pumping force that pushes blood around the body, is small and weak. As well as this, the aorta, which carries blood from the left ventricle to the rest of the body, is deformed and thin. The condition used to be fatal within a few weeks, but it can now be corrected surgically. The Norwood Procedure redistributes the blood, making the right atrium pump blood to the lungs and the right ventricle pump blood to the body.
