Preventing extrinsic mechanisms of bioprosthetic degeneration using polyphenols

This study was to evaluate the impact of a polyphenols-based treatment on the extrinsic mechanisms responsible for early BHV degeneration. The hydrodynamic performance of the polyphenolic-treated and untreated T-GT commercial BHVs was assessed under simulated pulsatile flow in a Vivitro Pulse Duplicator System. The treatment is chemically stable, improves tissue extensibility, and effectively stabilizes glutaraldehyde.
