Textile Heart Valve Prosthesis: Fabric Long-Term Durability
The rapid developments and success in percutaneous vascular surgery over the last 2 decades, with the now common stent graft implantation, make this non invasive technique attractive today even for heart valve replacement 1. A major requirement for the use of the method is that the heart valve prosthesis is flexible enough to be folded into the lumen of small diameter catheter. The purpose of this research was to study the long term fatigue behavior of woven polyester fabrics, which could be suitable for engineering heart valve prostheses. The results obtained show how flexural properties change with fatigue time, which reflects directly on the suitability of a given fabric in such devices.
