Relationship between fibre orientation and tensile strength of natural collagen membranes for heart valve leaflets [PDF]
Heart valve prostheses are used to replace native heart valves which that are damaged because of congenital diseases or due to ageing. Biological prostheses made of bovine pericardium are similar to native valves and do not require any anticoagulation ...

Dynamic Analysis of the Bioprosthetic Heart Valve on Different Fixation
This paper constructs the bioprosthetic valve leaflets’ parametric model via computer aided design, a series of accurate parameters of the bioproshtetic heart valve, such as such as radius of the sutural ring, height of the supporting stent and ...
