Abstract
In order to improve long-term durability of bioprosthetic heart valve, stress distribution of bioprosthetic heart valve leaflets with different shapes and suture density under the same load is analyzed and compared based on finite element method.The finite element analysis results are compared with each valve model, it shows that suture density has a significant effect on the dynamic behavior of the bioprosthetic heart valve, which may lead not only to different stress peak values, but also to different stress distributions and deformation. This work can be very helpful when manufacturing the bioprosthetic heart valve.
