Then he poked some fun at the situation.

In a statement released by the hospital, Faucette’s wife, Ann, said her husband “knew his time with us was short and this was his last chance to do for others. He never imagined he would survive as long as he did.”The Maryland team last year performed

of a heart from a genetically altered pig into another dying man. David Bennett survived two months before that heart failed, for reasons that aren’t completely clear althoughlater were found inside the organ. Lessons from that first experiment led to changes, including better virus testing, before the second attempt.“Mr. Faucette’s last wish was for us to make the most of what we have learned from our experience,” Dr. Bartley Griffith, the surgeon who led the transplant at the University of Maryland Medical Center, said in a statement.

Attempts at animal-to-human organ transplants — called xenotransplants — have failed for decades, as people’s immune systems immediately destroyed the foreign tissue. Now scientists are trying again using pigs genetically modified to make their organs more humanlike.Faucette, a Navy veteran and father of two from Frederick, Maryland, had been turned down for a traditional heart transplant because of other health problems when he came to the Maryland hospital, out of options and expressing a wish to spend a little more time with his family.

In mid-October, the hospital said Faucette had been able to stand and released video showing him working hard in physical therapy to regain the strength needed to attempt walking.

Cardiac xenotransplant chief Dr. Muhammad Mohiuddin said the team will analyze what happened with the heart as they continue studying pig organs.ever transplanted into people came from animals born on this special research farm in the Blue Ridge mountains – behind locked gates, where entry requires washing down your vehicle, swapping your clothes for medical scrubs and stepping into tubs of disinfectant to clean your boots between each air-conditioned barn.

“These are precious animals,” said David Ayares of Revivicor Inc., who spent decades learning to clone pigs with just the right genetic changes to allowThe biosecurity gets even tighter just a few miles away in Christiansburg, Virginia, where a new herd is being raised – pigs expected to supply organs for formal studies of animal-to-human transplantation as soon as next year.

This massive first-of-its-kind building bears no resemblance to a farm. It’s more like a pharmaceutical plant. And part of it is closed to all but certain carefully chosen employees who take a timed shower, don company-provided clothes and shoes, and then enter an enclave where piglets are growing up.Behind that protective barrier are some of the world’s cleanest pigs. They breathe air and drink water that’s better filtered against contaminants than what’s required for people. Even their feed gets disinfected – all to prevent them from picking up any possible infections that might ultimately harm a transplant recipient.
