The St. Jude Medical Trifecta valve, a heart valve with stented tissue, has unique pericardial tissue leaflets that are attached on the exterior portion of the stented valve and allow it to open efficiently and more fully, so that it performs like a real heart valve. The St. Jude Medical Trifecta is a next-generation heart valve that complements the St. Jude Medical Epic? and Biocor? tissue valves. The device has been designed to give physicians more control by providing outstanding results and performance in the areas of implantability, durability and hemodynamics. The Trifecta valve mimics the blood flow of a healthy heart valve, offering exceptional hemodynamic performance and thus improving the quality of life of patients. The valve has been created for positioning exclusively in an aortic position, and delivers better EOAs that give pressure gradients in single digits. The Trifecta valve was designed for performance and long-term durability, and has done well in vitro tests.
