Why the study?
Current prosthetic valves do not match native valve hemodynamics, requiring trade-offs between durability, thrombogenicity, and bleeding risk that require long-term follow-up data to evaluate.
Does mechanical valve replacement compared to bioprosthetic valve replacement improve long-term survival in patients undergoing surgical valve replacement?
Observational (n=681)

Does mechanical valve replacement compared to bioprosthetic valve replacement improve long-term survival in patients undergoing surgical valve replacement?
Both mechanical and bioprosthetic valves demonstrate excellent long-term survival, though bioprosthetic valves are associated with a higher incidence of structural valve degeneration.
