Structured PICO

Population

Porcine aortic valve leaflets (circumferential and radial strips)

Intervention

Fixation in glutaraldehyde and formaldehyde, with or without pressure

Outcome

Tensile viscoelastic properties (stress-strain, hysteresis, tensile strength, stiffness, extensibility, plastic deformation, stress relaxation, creep)surrogate

Pressure fixation of porcine aortic valves preserves stress-strain properties and prevents plastic deformation compared to fixation without pressure.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Pressure fixation may preserve bioprosthetic valve mechanics; hypothesis-generating for durability, should not yet change practice.
