Since the first implant in 1982, the Hancock® II valve has provided more than 25 years of excellent hemodynamic performance and durability.1
The Hancock® II porcine bioprosthesis is a second-generation valve that can be used in either aortic or mitral positions. The Hancock II Ultra® valve, featuring a reduced sewing cuff, is specifically designed for implant in a small aortic root.
The Cinch® Advanced Implant System, provided with Medtronic aortic and mitral stented bioprostheses, serves as an automated deflection system attached to the valve with sutures.
Adverse events potentially associated with the use of bioprosthetic heart valves include: angina, cardiac arrhythmia, cardiac dysrhythmias, death, endocarditis, heart failure, hemolysis, hemolytic anemia, hemorrhage (anticoagulant/antiplatelet-related), leak (transvalvular or paravalvular), myocardial infarction, nonstructural dysfunction (obstructive pannus ingrowth, suture dehiscence, inappropriate sizing, other), stroke, structural deterioration (calcification, leaflet tear, stenosis, other), thromboembolism, valve thrombosis. It is possible that these complications could lead to: reoperation, explantation, permanent disability, or death.
