Prosthetic Tissue Valves
Prosthetic Tissue ValvesOne disadvantage to a mechanical prosthetic valve is that the patient is required to undergo lifelong anticoagulation therapy. Although pyrolytic carbon has low thrombogenicity, valves made from this material still generate enough blood clots to warrant this type of therapy. Naturally occurring heart valves avoid the blood clotting problem as well as having better hemodynamic properties.Homografts are valves that come from a different member of the same species. These allografts typically come from cadavers and therefore consist of nonliving tissue. The advantage to containing no living cells is that the valves will not be rejected by the immune system of the host. The disad…
