The SynerGraft® Advantage
SynerGraft is CryoLife’s patented decellularization technology that serves as the foundation for the next generation of implantable biological tissues.
PRA Results-SynerGraft Process Vs Standard Process
Class I Alloantibodies After Implant
It is important to avoid elevated Panel Reactive Antibodies (PRA) in patients receiving SynerGraft cardiac tissue as some may ultimately require a heart transplant. While the link between immune response and allograft tissue performance is still being debated, there is evidence that an elevated PRA poses a significant risk to future organ transplant patients.

* Implantation of the SynerGraft treated pulmonary cardiac tissue reduces the risk for induction of HLA class I and class II alloantibodies based on PRA measured at up to one year, compared to the standard processed pulmonary cardiac tissue. Data has not been provided to evaluate the effect of reduced HLA class I and class II alloantibodies on the long-term durability, or long-term resistance to rejection by the patient.
