| Abstract: | This article aims at how to extend life span of bioprosthetic valve in a body. Through the finite element analysis to leaflets and the discussion of the stress distribution of bioprosthetic valve under the maximal loads in different conditions, we educe the major factors affecting stress distribution of leaflets. They are the character of leaflet material , geometry structure of leaflet shape and the factor of calcification. |
