Why the study?
Does the use of stentless bioprostheses reduce valve degeneration compared to stented bioprostheses or cryopreserved homografts in growing pigs?

Stentless bioprostheses show less calcific degeneration than stented bioprostheses in a growing pig model, suggesting potentially higher durability.
No takes yet. Share an insight, caveat, or question.
Stentless valves may reduce degeneration in growing models; hypothesis-generating and should not yet change prosthesis selection in patients.
Hazekamp et al. (1993) studied this question.
