Measure
Donation After Brain Death- Donor Heart Transplantation
If the heart offer is from a DBD donor, the heart will be retrieved per standard of care. DBD Donor Heart Transplantation: A technique of donor heart procurement.
Donation After Circulatory Death- Donor Heart Transplantation
If the heart offer is from a DCD donor, the heart will be retrieved using one of two strategies: Normothermic Regional Perfusion (NRP) or Direct Procurement and Perfusion (DPP). NRP procedures will be used to procure all DCD hearts unless contraindicated or prohibited by the donor hospital. In the event the donor hospital does not allow NRP for cardiac organ procurement, or the target number of eight DCD transplants with NRP has been achieved, DPP with the Organ Care System (OCS) should be utilized. DCD Donor Heart Transplantation: A technique of donor heart procurement. The TransMedics' OCS Heart technology is the only portable system available for ex-vivo maintenance of the donor heart in a metabolically active and beating state. It is currently FDA approved for procurement and transport.
