Does lack of durability of the Mitroflow valve affect survival?
In younger patients (aged < 75 years), the CE valves offer superior results to the M counterpart in valve replacement. However, in patients aged > 75 years, pericardial and porcine bioprostheses demonstrate equivalent durability, despite post-implantation tissue changes in the former material.
This study demonstrates that the individual contribution of each system appears dependent on the immediate environment. In foods Gbu appears to play the dominant role, while during infection OpuC is most important.
