Aortic valve bioprosthesis PERIMOUNT RSR

bovine tissue

PERIMOUNT RSR valve Carpentier-Edwards PERIMOUNT RSR aortic heart valve The Carpentier-Edwards PERIMOUNT RSR aortic valve combines a proven design with the benefits of pericardial tissue. Designed on the foundation of the PERIMOUNT aortic valve, with published clinical durability of up to 20 years PERIMOUNT aortic valves are supported by 17 years of proven hemodynamic stability Proven design Mathematically modeled, bioengineered design - optimized for hemodynamics, durability and implantability Flexible cobalt-chromium alloy stent - absorbs energy to reduce leaflet stress Three independent bovine pericardial leaflets - matched for thickness and elasticity to optimize stress distribution Indications The Carpentier-Edwards PERIMOUNT pericardial aortic bioprosthesis is intended for use in patients whose aortic valvular disease is sufficiently advanced to warrant replacement of their natural valve with a prosthetic one. It is also intended for use in patients with a previously implanted aortic valve prosthesis that is no longer functioning adequately and requires replacement. In the latter case, the previously implanted prosthesis is surgically excised and replaced by the replacement prosthesis.
