Study on biomechanical properties of bovine pericardium after freezing and thinning

Frozen and thinned bovine pericardium (BP) is a candidate transcatheter aortic valve (TAV) leaflet biomaterial for smaller-profile devices due to their reduced thickness now, however, their mechanical and structural properties still need to be to be fully test. In order to better understand their mechanical behavior, this study characterized compared with the mechanical properties of BP before and after freezing and thinning with porcine pericardium (PP).
