Textile heart valve prosthesis: Influence of the fabric parameters on its hydrodynamic performance in vitro.

The article describes a concept of heart valve prosthesis, based on the use of textile material. The goal of the work is to make a fabric prosthesis by using woven yarns made up of polyester. The method for prothesis manufacturing is described. Fabric prosthesis shows encouraging behavior in vitro such as good flexibility, reduced permeability with adapted fabric parameters.
