Detailed Description

The objective of this US National OHP Registry is to collect data on the post-transplant clinical outcomes of all donor hearts preserved and assessed on the OCS Heart System and to document the performance of the OCS Heart device in the real-world setting after FDA approval in the US.

The US National OHP Registry will enroll all heart transplant recipients who are transplanted with an OCS-perfused donor heart in the Registry. Patients' clinical outcomes will be followed up to five years post-transplant, loss to follow up, or death, whichever occurs first.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
OCS Heart Transplant Recipients
All heart transplant recipients who are transplanted with an OCS perfused donor heart are eligible for this registry.
Device: OCS Heart

The TransMedics® Organ Care System (OCS) Heart System is an FDA approved portable extracorporeal heart perfusion and monitoring system.

The OCS Heart System's innovative technology was designed to comprehensively overcome the historical limitations of cold storage. The OCS Heart System expands the utilization of donor hearts by enabling the use of donor hearts deemed unsuitable for procurement and transplantation at initial evaluation due to limitations of cold static cardioplegic preservation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recipients' patient and graft survival
Time Frame: Up to 5 years post-transplant
Recipients' patient and graft survival rates will be the primary clinical outcomes measures for all OCS Heart transplanted recipients compared to recipients receiving heart transplants using non-OCS preservation methods (cold static storage or other perfusion devices or a combination of both). This data will be obtained directly from UNOS/OPTN database.
Up to 5 years post-transplant
