Heart transplantation remains the ultimate treatment strategy for neonates and children with medically refractory end-stage heart failure and utilization of donors after circulatory death (DCD) can expand th donor pool. We have previously shown that mitochondrial transplantation preserves myocardial function and viability in neonatal swine DCD hearts to levels similar to that observed in donation after brain death (DBD). Herein, we sought to investigate the transcriptomic and proteomic pathways implicated in these phenotypic changes using ex situ perfused swine hearts.

Methods: This is a single-center retrospective review of patients with heterotaxy syndrome undergoing single-ventricle palliation or primary or staged biventricular repair from 1998 to 2018.
The protocol here provides a simple, highly replicable methodology to induce in situ acute regional myocardial ischemia in the rabbit for non-survival and survival experiments. New Zealand White adult rabbit is sedated with atropine, acepromazine, butorphanol, and isoflurane. The animal is intubated and placed on mechanical ventilation.

Herein, we investigate the efficacy of mitochondrial transplantation for the preservation of myocardial function and viability in neonatal and pediatric porcine DCD heart donation.
Methods: Circulatory death was induced in neonatal and pediatric Yorkshire pigs by cessation of mechanical ventilation.
