Key result
Stentless aortic xenografts provide more physiologic hemodynamics and may improve long-term survival compared to stented bioprostheses, though expected durability advantages have not been fulfilled.

Supports use in complex root pathology; leaves open whether durability or survival advantages hold versus modern stented valves.
Do stentless aortic xenografts improve hemodynamics, durability, and survival compared to stented bioprostheses in patients requiring aortic valve replacement?
Stentless aortic valves offer excellent hemodynamics and versatility in complex aortic root pathology, though their durability advantage over modern stented valves remains unproven.
Giovanni Battista Luciani (2004) conducted a review in Aortic valve disease. Stentless aortic xenografts vs. Stented bioprostheses was evaluated. Stentless aortic xenografts provide more physiologic hemodynamics and may improve long-term survival compared to stented bioprostheses, though expected durability advantages have not been fulfilled.
