Thankfully, they'll all miss. "He proved to be a brave and noble patient who fought all the way to the end," surgeon Bartley Griffith, who performed the transplant, said in a statement released by the hospital.

The pig had 10 genetic alterations: one was designed to prevent the recipient's body from rejecting the pig heart, another aimed to keep the pig's heart from growing post-transplant.

The first man to receive a transplanted pig's heart died of heart failure due to several factors, not organ rejection, leading the doctors involved in the trial to call it a success. The heart used in the transplant came from a pig with several genetic modifications, including some to knock out genes that trigger the human immune system. But his condition deteriorated, leaving doctors "devastated".

This is what would happen if a regular pig organ were used for transplant; all humans have roughly one per cent of their antibodies devoted to attacking what are called alpha-gal sugars.

The heart was beating too powerfully for its fragile new owner, and it had to be chemically slowed. Once maimed, a king cannot rule.

The first kidney transplant with long-term success was performed on the identical twins Ronald and Richard Herrick, two days before Christmas in 1954, by Joseph Murray, in Boston.
