Abstract
BACKGROUND: Heart donation (HD) by those with death determination by circulatory criteria (DDCC) has been proposed as a method to increase the heart donor pool in response to the growing need for heart transplantation (HT). However, the potential level of HD after DDCC in the province of Québec has not yet been reported. This study aims to assess the suitability for HD among donors with DDCC, and to estimate its impact on HT activity. METHODS: Donation records by those with DDCC in the province of Québec, from January 2016 to December 2020, were retrospectively reviewed for donor and predonation characteristics. Predetermined exclusion criteria were used to evaluate eligibility for HD. RESULTS: Of the 122 patients with DDCC who were included, 42 (34%) were identified as potentially-eligible heart donors. The median age of potentially-eligible donors was 52 years; 60% were female; and the most prevalent causes leading to organ donation in this group were medical aid in dying (26%), traumatic brain injury (26%), and anoxia (24%). A 19% increase (42 of 225) in potential HT activity was estimated using strict criteria. In only one case did functional warm ischemia time exceed the 30-minute limit. CONCLUSIONS: Using those with DDCC as a new source of heart donors can significantly increase the volume of heart donation in the province of Québec. Implementing an HD program for those with DDCC in Québec may reduce waiting time and increase the number of heart recipients.
