Donor Heart Preservation at 10 °C Outperforms 4-8 °C With Improved Early Graft Function in Adult Heart Transplantation: A Vanderbilt and Duke Multicenter Study.

Among 365 recipients, 113 received allografts preserved at 10 °C and 252 at 4-8 °C.

The 10 °C group had higher donor and recipient risk profiles, including older donors (37 [28-43] versus 31 [24-39] years; P =0.004), greater donor-recipient sex mismatch, and more frequent donor undersizing by predicted heart mass ratio.

Recipients in this cohort were older and had more re-sternotomies and higher serum creatinine levels at transplant.

Patients in the 4-8 °C group were more often listed as Status 2.
