Aortic Valve Replacement with Stentless Porcine Bioprostheses
Why the study?
Do stentless porcine bioprostheses improve hemodynamics and clinical outcomes compared to stented bioprostheses in patients requiring aortic valve replacement?
Population

Implication
May support stentless valves for hemodynamic gains in AVR; leaves open randomized confirmation of durability and survival benefits.
Structured PICO
Do stentless porcine bioprostheses improve hemodynamics and clinical outcomes compared to stented bioprostheses in patients requiring aortic valve replacement?
P
Population
Patients requiring aortic valve replacement, including those with degenerative calcification of a tricuspid aortic valve or bicuspid aortic valve.
I
Intervention
Stentless porcine bioprostheses (e.g., Toronto SPV, Medtronic Freestyle)
C
Comparator
Stented bioprostheses
Stentless porcine bioprostheses offer excellent hemodynamic performance and potentially lower risks of cardiac death and complications compared to stented valves, though long-term durability is still unknown.
Limitations
- Durability of stentless valves compared to stented ones remains unknown
