Structure and Rheological Properties of Bovine Aortic Heart Valve and Pericardium Tissue: Implications in Bioprosthetic and Tissue-Engineered Heart Valves

Figure 5

Analysis of creep recovery test applying stress at 5 kPa and 0.5 kPa on the samples of bovine aortic valve and pericardium tissue. The Y axis shows the creep compliance valve with respect to time. The creep compliance of fresh sample for both the stresses at 0.5 kPa and 5 kPa is much higher than the fixed samples of bovine aortic heart valve and pericardium tissue at stresses of 0.5 and 5 kPa.
