Abstract
This brief communication about machine perfusion of potential human donor hearts describes its historical development. Included in the review are both the isolated perfusion of donor hearts retrieved from heart beating and non-heart-beating donors. Additionally, some detail of in-situ (within the donor body) normothermic regional reperfusion of the heart and other organs is given. This only applies to the DCD donor heart. Similarly, some detail of ex-situ (outside the body) heart perfusion is offered. This article covers the entire history of the reperfusion of donor hearts. It takes us up to the current day describing 6 years follow-up of these donor machine perfused hearts. These clinical results appear similar to the outcomes of heart beating donors if reperfusion is managed within 30 min of normothermic circulatory determined death. Future developments are also offered. These are 3-fold and include: i. the pressing need for objective markers of the clinical outcome after transplantation, ii. the wish for isolated heart perfusion leading to improvement in donor heart quality, and iii. a strategy to safely lengthen the duration of isolated heart perfusion.
