Comprehensive Options for Pediatric Donation After Circulatory Death Donors

Abstract

Cardiac transplant represents the only definitive strategy for children with end-stage heart failure. Pediatric patients face significant wait-list times and resultant mortality due to a worsening shortage of hearts available for transplant. Donation after circulatory death (DCD) represents an opportunity to increase the number of hearts available to pediatric recipients by 30%. DCD donation has been historically limited in application due to logistical challenges and ethical concerns. A systematic review was carried out using the Cochrane Handbook. Eligible studies were identified using MEDLINE (via OVID), Embase (Elsevier), Cochrane Library/Cochrane Central Register of Controlled Trials (CENTRAL; Wiley), and Web of Science Core Collection (Clarivate). This search was conducted by a professional medical librarian in consultation with the author team and validated against a set of pre-selected articles. This resulted in 438 articles, which were screened based on title and abstract by 2 independent authors. Full-text review was subsequently performed, resulting in 21 articles. Agreement for inclusion included pediatric DCD, published in English, and complete manuscript availability. Four principal techniques were identified for pediatric DCD: rapid procurement and static cold storage, organ care systems, normothermic regional perfusion, and on-table reanimation. These all portend unique advantages and disadvantages and have largely evolved due to limitations of prior techniques. Providing a comprehensive approach to pediatric cardiac DCD is the most effective method to ensure organ stewardship, minimize wait list mortality, and mitigate ethical concerns associated with pediatric DCD.
