Pig To Human Heart Transplants 'Possible Within Three Years' (theguardian.com) 83

An anonymous reader quotes a report from The Guardian: Adapted pig hearts could be transplanted into patients within three years, according to a report citing the surgeon who pioneered heart transplantation in the UK. On the 40th anniversary of the first successful heart transplant, Sir Terence English told The Sunday Telegraph that his protege from that operation would try to replace a human kidney with a pig's this year. "If the result of xenotransplantation is satisfactory with porcine kidneys to humans, then it is likely that hearts would be used with good effects in humans within a few years," the 87-year-old said. "If it works with a kidney, it will work with a heart. That will transform the issue." The anatomy and physiology of a pig's heart is similar to that of a human's, so they are used as models for developing new treatments.

      IIRC, both Judaism and Islam explicitly allow you to break kosher or halal rules if it is a matter of life and death. I'm not Jewish, but I would assume that this would be kosher under that logic because no one is going to get a pig transplant for the fun of it.

      Whether or not hard-line, stubborn, fundamentalist, conservative boneheads will throw their lives away anyway, like Jehovah's Witnesses sometimes do with blood transfusions, is yet to be seen. Far as I'm concerned, provided no minors die for their parents' superstitions, it's their bodies and their funeral.

      Interesting, I had not read that before. I am aware that one of the major restrictions with using pig hearts for transplant is that pigs grow much faster than humans do, hence you can't use piglet hearts in children and/or adolescents as the heart will rapidly outgrow its attachments. I'd also be concerned about longevity, as a 'ripe old age' for a pig is only 20 years - though I guess if you're dying due to heart problems any extra years are a bonus.
