Study Details

Study Description

Brief Summary

The OCS™ Heart System will be used to preserve and assess donor hearts that do not meet current standard donor heart acceptance criteria for transplantation in this continued access protocol.

Condition or Disease Intervention/Treatment Phase
  • Device: OCS Heart System
N/A

Detailed Description

To provide additional data evaluating the safety and effectiveness of the OCS™ Heart System to preserve and assess donor hearts that do not meet current standard donor heart acceptance criteria (as identified above) for transplantation to potentially improve donor heart utilization for transplantation at a range of transplant centers in the U.S. and to permit patients and physicians access to the OCS Heart System while a PMA application is under preparation and review.

Arms and Interventions

Arm Intervention/Treatment
Experimental: OCS Preservation

Device: OCS Heart System
The OCS Heart System preserves the heart in a near-physiological, beating state by perfusing the heart with a warmed, donor-blood based perfusate that is supplemented with nutrients and oxygen in a controlled and protected environment

Outcome Measures

Primary Outcome Measures

  1. Survival [30 days]

    Patient survival post transplant

  2. Absence of severe PGD [24 hours post heart transplant]

    Absence of severe primary heart graft dysfunction of left and/or right ventricle in the first 24 hours post transplant

Secondary Outcome Measures

  1. Survival [30 days]

    Patient and graft survival

  2. Incidence of severe PGD [24 hours post transplant]

    Incidence of severe primary heart graft dysfunction of left and/or right ventricle in the first 24 hours post heart transplant

  3. Donor heart utilization rate [24 hours post-transplant]

    The proportion of eligible donor hearts that were successfully transplanted after preservation and assessment on the OCS Heart System

Other Outcome Measures

  1. Survival [6 and 12 months]

    Patient survival at 6 and 12 months post-transplant

  2. Incidence of primary graft failure [Through 12 months post transplant]

    Incidence of primary graft failure requiring re-transplantation

  3. ICU stay [Through hospital discharge, estimated to be 14 days]

    Duration of initial post-transplant ICU stay in days

  4. Hospital stay [Through hospital discharge, estimated to be 30 days]

    Duration of initial post-transplant hospital stay in days
