According to the University of Maryland School of Medicine, the heart had seemed healthy for the first month but began showing signs of rejection in recent days. Faucette died Monday.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 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 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.Pig kidney recipient Towana Looney stands with transplant surgeons Dr. Jayme Locke, left, and Dr. Robert Montgomery, center, at NYU Langone Health.

Blacksburg, Virginia-based Revivicor provided Looney’s new kidney from a pig with 10 gene alterations. Its parent company, United Therapeutics said Tuesday it plans to file an application with the FDA “very soon” to begin clinical trials with that type of kidney.Looney was initially discharged on Dec. 6, wearing monitors to track her blood pressure, heart rate and other bodily functions and returning to the hospital for daily checkups before her medication readmission. Doctors scrutinize her bloodwork and other tests, comparing them to prior research in animals and

in hopes of spotting an early warning if problems crop up.“A lot of what we’re seeing, we’re seeing for the first time,” Montgomery said.
