Rate-Dependent and Relaxation Properties of Porcine Aortic Heart Valve Biomaterials

Objective: This work evaluates the rate-dependent and relaxation properties of native porcine heart valves, glutaraldehyde fixed porcine pericardium, and decellularized sterilized porcine pericardium. Methods: Biaxial tension testing was performed at strain-rates of 0.001 s -1 , 0.01 s -1 , 0.1 s -1...
