Ross Procedure
A surgical technique that uses the patient's own pulmonary valve to replace a diseased aortic valve.
Full Definition
The Ross procedure is a complex cardiac surgical operation in which the patient's native pulmonary valve is harvested and transplanted to replace a diseased aortic valve, while a homograft or prosthetic valve replaces the pulmonary valve. Named after British surgeon Donald Ross, this procedure is primarily used in children and young adults with aortic valve disease who require a living, growing valve replacement. The procedure offers the advantage of using autologous tissue that can potentially grow with the patient and does not require anticoagulation. However, it carries the risk of requiring future intervention on both the neo-aortic and pulmonary positions.
Usage
Usage note: Capitalize 'Ross' as it is named after a person; 'procedure' and 'operation' are interchangeable.
