Why does the Ross procedure work?
The Ross procedure is a very effective treatment solution for a damaged aortic valve because the pulmonary valve is under less stress and therefore a replacement valve in this position has a far greater chance of succeeding.
During the Ross procedure, the patient's aortic valve is swapped with their own pulmonary valve and the pulmonary valve is replaced with a donor valve. Since the aortic valve is responsible for pumping all the blood back into the body, the stress on this valve is far greater and therefore, a replacement aortic valve is less likely to work. The two valves are similarly shaped which means they can be "swapped out".
