摘要：
In this study, biomechanical properties of porcine pericardium and aortic valvular leaflet tissue were comparatively investigated in tensile tests. Fresh porcine pericardium and aortic valves were harvested from domestic pig cadavers. Specimens were prepared from either native or HDI-fixed tissue. Uniaxial tensile testing was conducted in physiological saline solution at 37 degrees C. The results show a clear distinction regarding the biomechanical behaviour of native pericardium and aortic valvular leaflet tissue. It could be demonstrated that the concentration of HDI and the fixation time influence the properties of native pericardium towards the biomechanical behaviour of aortic valvular leaflet tissue.
