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 than the one on the pulmonary valve and therefore, a replacement aortic valve is less likely to work.

Because the demand on the pulmonary valve is less - as it does not need to generate a lot of force to push blood to the lungs - a replacement valve can be more likely to succeed. The two valves are similarly shaped which means they can be "swapped out".
