Abstract
The present invention provides a prosthetic heart valve that includes biologically active agents that retard or prevent the infiltration of fibrous tissue ('pannus') from the host into the structure of the prosthetic valve. Preventing or decreasing the overgrowth of the prosthetic valve by pannus reduces the complications associated with the implantation and use of prosthetic heart valves.
