NORWOOD Procedure –
1-The lower section of the pulmonary artery is removed. The pulmonary valve is connected to the aorta to increase oxygen-rich blood flow to the body.
2-Atrial Septostomy [ostomy=an artificial hole, septal=wall that separates the right and left atria] They remove the wall between the left and right atria (creating a large opening) so oxygen-rich blood can more easily get to the aorta and out to the body.
3-A shunt is placed between one of the branches of the Aorta to the pulmonary artery allowing blood to flow into the lungs (at a low enough pressure that the lungs don’t get hurt). This is a temporary measure that allows time for the patient to grow with fewer complications until the heart is ready for the next surgical step.
4-The Aortic Arch is repaired. The section with severe narrowing is removed. The PDA is closed and the aortic arch is sewn or patched into the descending aorta to restore normal blood flow of oxygen-rich blood out to the body
