The Ross Operation in the Adult: What, Why, and When?

The normal aortic valve is a sophisticated and dynamic structure whose equal replacement has not yet been actualized by modern technology. The use of the pulmonary autograft as a substitute for a diseased aortic valve (the Ross procedure) has been in practice for several decades in many types of patient. In the adult, it has not been adopted widely due to concerns about its technical challenge, complex perioperative care, the development of pulmonic valve disease, and concerns about long-term dilatation of the neo-aortic root, among others. There has been a substantial body of data showing excellent long-term survival, freedom from reoperation, and quality of life, in contradistinction to these preconceptions. The authors review the available data pertinent to these questions to further define the role of the Ross procedure in the adult cardiac surgery patient.
