Hybrid textile heart valve prosthesis: preliminary in vitro evaluation

Transcatheter aortic valve implantation (TAVI) is nowadays a popular alternative technique to surgical valve replacement for critical patients. Biological valve tissue has been used in these devices for over a decade now with over 100,000 implantations... ...The purpose of the present work is to study in vitro the mechanical as well as the hydrodynamic behavior of a hybrid elastic textile valve device combining non-deformable PET yarn and elastic polyurethane (PU) yarn... ... times for each valve. Durability testing of the devices. The prototypes were tested on a commercial fatigue apparatus (Vivitro Labs Inc., Victoria, Canada) equipped with an electromagnetic drive mechanism. Six valve prototypes ...
