I think this is an important question. Donation of organs after death can happen when people are declared dead due to brain death, or when they are declared dead due to classical criteria including cardiac death. "Donation after cardiac death", as you might imagine, seems a bit weird when the heart is the organ being donated. And so it's a recent invention for the heart (though it has been around for a long time for other organs such as the kidney[1]). There is a free access article from 2018 about the necessity and ethical considerations of cardiac donation after cardiac death in Circ: Heart Failure [2]. 1 = https://health.ucdavis.edu/transplant/nonlivingdonors/donation-after-cardiac-death.html https://health.ucdavis.edu/transplant/nonlivingdonors/donati... 2 = https://www.ahajournals.org/doi/10.1161/CIRCHEARTFAILURE.118.004884 https://www.ahajournals.org/doi/10.1161/CIRCHEARTFAILURE.118...
