Temperature-controlled heart preservation system vs ice for primary graft dysfunction
Official title: Prospective Reduction Of Transplant Complications Through Enhanced Preservation Therapy to Prevent Primary Graft Dysfunction
Run by University Health Network, Toronto · NCT07230886 · Data updated 2026-11-12
This study tests whether using the Xo Port Organ Preservation System can reduce severe graft dysfunction after heart transplant compared with traditional ice storage in adult recipients.

Is this trial a fit for you?
✓Likely a good fit
Adult heart transplant recipients receiving donor hearts after brain death, eligible for randomization to either Xo Port preservation or ice storage.
✕Probably not a fit
Patients whose donor heart is not compatible with the preservation system or who do not meet randomization criteria may not see a benefit.

What this trial studies
The PROTECT-PGD Pilot is a multicenter, randomized, blinded feasibility trial that compares a novel temperature-controlled heart preservation system to standard ice storage. It aims to see if the Xo Port system can lower the rate of severe primary graft dysfunction within 24 hours after transplant and improve composite efficacy endpoints. The study also checks whether the trial procedures can be carried out as planned and if any protocol deviations occur. Participants will be followed for 90 days with questionnaires and blood tests aligned to standard post-transplant care. If feasibility is demonstrated, participants may be included in a subsequent full-scale trial.
Why it matters
Potential benefit: If successful, the Xo Port system could reduce early graft dysfunction and improve transplant outcomes.
How similar studies have gone: Prior feasibility work supports evaluating temperature-controlled preservation approaches, but this exact system and design are being tested in a pilot study.
