Currently one of the leading causes of death worldwide is heart diseases which include calcification of heart valves and vascular aneurysm. There are many biomaterials that can substitute pathologically altered tissue, however, none of them is as perfect as native tissue. Currently, scientists are looking for new biomaterials that can be successfully implanted without exposing the patient to reoperation. Each material introduced into an organism must afford sufficient mechanical and biochemical properties and meet the criteria of the biomaterial. The most important mechanical properties include fatigue strength, longitudinal and transverse tensile strength and elastic modulus otherwise known as Young's modulus. Materials intended to take over the function of natural tissue materials should be characterized to the greatest extent by similar mechanical properties to them. Therefore this study provides an overview of selected methods for the tensile tests characterizing the mechanical properties of the heart valves, pericardium and porcine aortas. We also present results of our study of mechanical properties of natural porcine tissues.
