This review summarizes methodologies for assessing the mechanical properties of mammalian pericardial patches to optimize biomaterial selection for prosthetic heart valves.
Review of pericardial testing methods leaves open optimal species selection for valve durability; standardized comparative protocols needed.
Mammalian pericardia are currently used for the production of percutaneous prosthetic heart valves. The characteristics of biological tissues largely influence the durability of prosthetic devices used in the percutaneous approach and in traditional surgery, too. This paper reviews methodologies employed to assess and compare mechanical properties of pericardial patches from different mammalian species in order to identify the biomaterials adequate for manufacturing prosthetic heart valves.
