Worldwide, the majority of heart transplant organs are from donation after brain death. However, the shortage of suitable donors places severe limitations on this route. One option to increase the donor pool is to use organs from donation after circulatory death (DCD). Transplant centers for solid organs have been using DCD organs for years. At this time, 40% of solid organ transplantation in the United Kingdom uses organs from DCD. Use of DCD for solid organ transplants in Canada is also rising. Recently, there has been interest in using DCD organs for heart transplantation. The authors will discuss their experience of 4 heart transplants with organs from DCD donors after normothermic regional perfusion (NRP). The authors' first heart transplant using a DCD organ was in January 2020, and the fourth was in March 2020, just before the coronavirus disease 2019 (COVID-19) pandemic. The authors' protocol using NRP allows adequate evaluation of the donor heart to confidently determine organ acceptance. The co-location of the donor and the recipient in neighboring operating rooms limits ischemic times. Avoidance of an expensive ex vivo organ perfusion machine is an additional benefit for programs that may not have the resources required to purchase and maintain the machine. Some hospitals may not have the resources and space to be able to co-locate both the donor and recipient. Use of cold storage may be an option to transport the procured organ, similar to donation after brain death organs. The authors hope that this technique of NRP in DCD donors can help further increase the donor pool for heart transplantation in the United States.
在全球范围内,大多数心脏移植器官来自脑死亡后的捐献。然而,合适供体的短缺严重限制了这一途径。增加供体库的一种选择是使用心脏死亡后循环供体(DCD)的器官。实体器官移植中心多年来一直在使用 DCD 器官。目前,英国 40%的实体器官移植使用的是 DCD 器官。加拿大使用 DCD 进行实体器官移植的数量也在增加。最近,人们对使用 DCD 器官进行心脏移植产生了兴趣。作者将讨论他们在常温区域灌注(NRP)后使用 DCD 供体进行 4 例心脏移植的经验。作者使用 DCD 器官进行的第一例心脏移植是在 2020 年 1 月,第四例是在 2020 年 3 月,就在冠状病毒病 2019(COVID-19)大流行之前。作者使用 NRP 的方案允许对供体心脏进行充分评估,从而有信心确定器官是否可以接受。供体和受体在相邻手术室中的共处将限制缺血时间。避免昂贵的离体器官灌注机能为可能没有购买和维护机器所需资源的项目带来额外的好处。一些医院可能没有资源和空间来同时安置供体和受体。冷储存可能是运输获取器官的一种选择,类似于脑死亡后的捐献器官。作者希望 DCD 供体中的 NRP 技术能够帮助进一步增加美国心脏移植的供体库。
