Intriguing article in MIT Technology Review, “Transplant surgeons revive hearts after death.”
These days, we’re familiar with heart transplants from brain-dead patients into others needing a new, healthy heart.
But in a new experimental breakthrough, successes have been achieved in transplanting the hearts of those not brain dead. Yes, there are procedural and ethical issues involved.
Mind you, this involves actual human hearts, not 3-D printed replacements, or bits of heart tissue grown in labs from human stem cells.
But the possibility raises some issues of medical ethics to be explored: if the donor is not brain dead, when and by what criteria can the heart be removed?
Rather than dig in deeply here, I’ll refer you to the article itself. You’ll see a “reanimated” donated heart actually beating outside the bodies of both donor and recipient. Here's the link.
