Transplantation of a heart donated after circulatory death via thoraco-abdominal normothermic regional perfusion and results from the first Spanish case.

BACKGROUND: Controlled donation after circulatory death (cDCD) has emerged as one of the main strategies for increasing the organ donor pool. Because of the ischemic injury that follows the withdrawal of life-sustaining therapies, hearts from cDCD donors have not been considered for transplantation until recently. The ex-situ perfusion of hearts directly procured from cDCD donors has been used to allow the continuous perfusion of the organ and the assessment of myocardial viability prior to transplantation. Based on our experience with abdominal normothermic regional perfusion in cDCD, we designed a protocol to recover and validate hearts from cDCD donors using thoraco-abdominal normothermic regional perfusion without the utilization of an ex-situ device. CASE PRESENTATION: We describe the first case of a cDCD heart transplant performed with this approach in Spain. The donor was a 43-year-old asthmatic female diagnosed with severe hypoxic encephalopathy. She was considered a potential cDCD donor and a suitable candidate for multiorgan procurement including the heart via thoraco-abdominal normothermic regional perfusion. The heart recipient was a 60-year-old male diagnosed with amyloid cardiomyopathy. Cold ischemia time was 55 min. The surgery was uneventful. CONCLUSIONS: This case report, the first of its kind in Spain, supports the feasibility of evaluating and successfully transplanting cDCD hearts without the need for ex-situ perfusion based on the use of thoraco-abdominal normothermic regional perfusion opening the way for multiorgan donation in cDCD.

Can We Improve the Effectiveness of the Spanish Nondirected Donation Program?

BACKGROUND: A nondirected altruistic living kidney donor is a person who wants to donate a kidney to anyone in need. In 2010, the Spanish National Transplant Organization developed a national protocol to make the assessment of every potential nondirected living kidney donor. The aim of this study was to describe the potential donor pool and its characteristics and the overall effect of the program. MATERIAL AND METHODS: A retrospective analysis was performed using data from the Spanish National Registry of Transplant Activity, and the Nondirected Donors National Database, between 2010 and 2017. Data related to sociodemographic characteristics, main motivations toward donation, and causes of dismissal were collected from all potential donors. The assessment of each candidate was carried out in a step-by-step process based on the national protocol. RESULTS: Two hundred seventy-two people contacted us, showing interest in the nondirected kidney donation, only 203 people underwent the early triage, and 16 of them successfully completed the assessment proces s, representing 8% of the total. The main motivation toward anonymous donation (n = 161) was: social awareness (22%) and to improve the quality of life of other people (9%). One hundred eighty-two candidates did not proceed, due to medical and psychological contraindications (42%) or donor refusal after specific information about the donation process (33%). The number of utilized nondirected altruistic living donors was 13 out of 203 (6%) of the candidates who began the early triage. Twelve transplant chains and a direct donation were performed, which made 38 kidney transplants possible (2.9 transplants per nondirected donor). CONCLUSIONS: We have to continue working to optimize our program. Our next steps will be to review the evaluation process, to detect areas for improvement, to understand why we lost many possible donors, and to ascertain if any of the reasons could be avoided.
