Authors' conclusion

Preservation of cardiac allografts at 10 °C may yield superior early graft function compared with 4-8 °C static cold storage. However, further prospective studies are required to delineate the optimal donor heart preservation temperature.

Study context

Population
Adult single-organ, donation-after-brain-death heart transplant recipients at 2 high-volume centers, January 2020 to April 2025
Participants
365 recipients
Comparison
allografts preserved at 10 °C versus 4-8 °C static cold storage
  • 10 °Cn = 113
  • 4-8 °Cn = 252

Main finding
