Artificial tissue valves are less durable than artificial mechanical valves but they require less anticoagulation than mechanical valves and, thus, are associated with fewer bleeding complications. The past 40 years have witnessed persistent efforts to manufacture either a mechanical valve that does not require warfarin therapy or a tissue valve with greater long-term durability. The ATS 3f Aortic Bioprosthesis was developed specifically to address the durability problem with previously designed artificial tissue valves.
