While it’s too soon to know if the operation really will work, it marks a step in the decades-long quest to one day use animal organs for life-saving transplants. Doctors at the University of Maryland Medical Center say the transplant showed that a heart from a genetically modified animal can function in the human body without immediate rejection.

The patient, David Bennett, a 57-year-old Maryland handyman, knew there was no guarantee the experiment would work but he was dying, ineligible for a human heart transplant and had no other option, his son told The Associated Press.

“It was either die or do this transplant. I want to live. I know it’s a shot in the dark, but it’s my last choice,” Bennett said a day before the surgery, according to a statement provided by the University of Maryland School of Medicine.

On Monday, Bennett was breathing on his own while still connected to a heart-lung machine to help his new heart. The next few weeks will be critical as Bennett recovers from the surgery and doctors carefully monitor how his heart is faring.

There’s a huge shortage of human organs donated for transplant, driving scientists to try to figure out how to use animal organs instead. Last year, there were just over 3,800 heart transplants in the U.S., a record number, according to the United Network for Organ Sharing, which oversees the nation’s transplant system.


“If this works, there will be an endless supply of these organs for patients who are suffering,” said Dr. Muhammad Mohiuddin, scientific director of the Maryland university’s animal-to-human transplant program.

But prior attempts at such transplants — or xenotransplantation — have failed, largely because patients’ bodies rapidly rejected the animal organ. Notably, in 1984, Baby Fae, a dying infant, lived 21 days with a baboon heart.

The difference this time: The Maryland surgeons used a heart from a pig that had undergone gene-editing to remove a sugar in its cells that’s responsible for that hyper-fast organ rejection. Several biotech companies are developing pig organs for human transplant; the one used for Friday’s operation came from Revivicor, a subsidiary of United Therapeutics.

“I think you can characterize it as a watershed event,” Dr. David Klassen, UNOS’ chief medical officer, said of the Maryland transplant.

As for the heart transplant, “He realizes the magnitude of what was done and he really realizes the importance of it,” David Bennett Jr. said. “He could not live, or he could last a day, or he could last a couple of days. I mean, we’re in the unknown at this point.”

we could be on the verge of eliminating the organ transplant list altogether, medical science is amazing.:wow:

who knows.. i didn't see any info on Immunosuppressant drugs being used.

unless some miscalculation or overlooked gene catches them by surprise, this might work long-term.:ld:

if he doesn't need any drugs after the surgery for the rest of his life then thats literally tens of thousands of dollars saved.:wow:
