Ice-cold storage or controlled hypothermia to preserve marginal grafts in high-risk heart transplantation.

Background: To evaluate the effectiveness of the Paragonix SherpaPak cardiac transport system (PSP) compared to the standard ice-cold storage (ICS) in extended-criteria donor grafts implanted in high-risk recipients.

Methods: Data of all HTx at the University Centers of Udine and Bologna, between January 2020 and December 2023, employing extended-criteria donors in high-risk HTx conditions were retrospectively analyzed. Patient outcomes and complications after HTx were assessed.
