The Maryland team last year performedof 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 although

later 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.

Many scientists hope xenotransplants one day could compensate for the huge shortage of human organ donations. More than 100,000 people are on the nation’s list for a transplant, most awaiting kidneys, and thousands will die waiting.Nov. 15, 2022: Zelenskyy unveils a 10-point peace plan at the G20 summit in Indonesia.
