The Ross Procedure is an option when the aortic valve needs to be
replaced. The patient's pulmonary valve is excised and used to replace the malfunctioning aortic valve, which is excised and discarded. This allows the patient's own tissue to be used in the more-stressful aortic position. The excised pulmonic valve is replaced by a cadaveric valve, which serves in the less-stressful pulmonic position.
