October 29, 2025 updated by: TransMedics

OCS Heart Perfusion (OHP) Post-Approval Registry

The objective of this post-approval registry is to provide additional real-world evidence of the performance of the OCS Heart System to preserve DBD and DCD donor hearts.

Study Overview

Status

Active, not recruiting

Conditions

Intervention / Treatment

Detailed Description

Multi-center, observational post-approval registry to:

  1. compare patient and graft survival of adult primary heart transplant recipients receiving DBD donor hearts perfused and assessed on the OCS Heart System compared to adult recipients of DBD donor hearts preserved using ischemic cold storage hearts (Control) at the same Registry centers over the same time period, and
  2. compare patient and graft survival of adult primary heart transplant recipients receiving DCD donor hearts perfused and assessed on the OCS Heart System compared to adult recipients of DBD donor hearts preserved using ischemic cold storage hearts (Control) at the same Registry centers over the same time period.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Sampling Method

Non-Probability Sample

Study Population

Participants will be adult primary heart transplant potential recipients on the waiting list for heart transplantation at the participating Registry centers.

Description

Inclusion Criteria:

  • Adult primary heart transplant recipients of DBD or DCD donor hearts perfused on the OCS Heart System.

Recipient Exclusion Criteria:

  • Concurrent (multi-organ transplant) or previous solid organ or bone marrow transplant; or
  • On renal dialysis at time of transplant.

Donor Exclusion Criteria (for DCD Donor Hearts only):

  • Warm ischemic time > 30 minutes (warm ischemic time is defined as: Time from when mean systolic blood pressure (SBP) is < 50 mmHg or peripheral saturation < 70% to aortic cross-clamp and administration of cold cardioplegia in the donor).

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
OCS DBD Heart Primary Analysis Population

200 adult primary heart transplant recipients of OCS perfused DBD donor hearts that meet the FDA-approved indication for use except for the following recipient exclusion criteria:

  • Concurrent (multi-organ transplant) or previous solid organ or bone marrow transplant; or
  • On renal dialysis at time of transplant

The TransMedics® OCS Heart System is a portable system available for ex-vivo maintenance of a donor heart in a metabolically active and beating state.

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.

OCS DCD Heart Primary Analysis Population

150 adult primary heart transplant recipients of OCS perfused DCD donor hearts that meet the FDA-approved indication for use except for the following recipient exclusion criteria:

  • Concurrent (multi-organ transplant) or previous solid organ or bone marrow transplant; or
  • On renal dialysis at time of transplant
  • Transplanted with DCD heart with warm ischemic time > 30 minutes (warm ischemic time is defined as: Time from when mean systolic blood pressure (SBP) is < 50 mmHg or peripheral saturation < 70% to aortic cross-clamp and administration of cold cardioplegia in the donor).

Other OCS Heart Analysis Population
Any/all other recipients of OCS Heart perfused donor hearts outside of the DBD and DCD indications above will be collected in the respective arm of this registry until the enrollment of the PAP of that arm is completed (200 for DBD and 150 for DCD).
