Abstract

In the current era of heart transplantation, machine perfusion strategies are emerging as potential additions to the armamentarium of a transplant unit. Donation after circulatory death (DCD) donor hearts assessed through normothermic machine perfusion (NMP) has helped expand the donor pool. Hypothermic machine perfusion (HMP) is emerging as an alternative strategy to traditional static cold storage (SCS) when a prolonged ischemic time is anticipated in brain dead (BD) donors, this is important in Australia where long distant procurement is vital. In this study we examine the outcomes in our unit where both forms of machine perfusion (NMP and HMP), as well as SCS is utilized for donor heart preservation, with a particular focus on severe primary graft dysfunction (sPGD) and mortality.
