A man from Maryland, United States of America undergoes genetically-modified pig heart in a world-first transplant and he is doing well three days after receiving the first-of-its-kind transplant surgery, the University of Maryland Medicine explained in an announcement on the 10th, Monday.
The patient identified as David Bennett had terminal heart disease, and the pig heart was “the last alternative,” according to the news. 57-year-old  Bennett was confirmed not fit for a normal heart transplant or an artificial heart pump after a series of medical examinations by the doctors.

“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 before the surgery, according to the release.
The US Food and Drug Administration granted emergency authorization for the surgery on December 31. Three genes that are behind for repulsion of pig organs by human immune systems were exterminated from the donor pig, and one gene was removed to stop colossal pig heart tissue growth. Six human genes behind immune acceptance were introduced.
Bennett’s medical experts will need to mount closed-door surveillance for immune system problems or other complications on him for days to weeks to see if the transplant was finally successful to offer lifesaving aids.
Hear The Doctors Who Did The transplant And The Chances Of Survival Analysis
“There are simply not enough donor human hearts available to meet the long list of potential recipients,” surgeon Dr. Bartley P. Griffith said in a statement. “We are proceeding cautiously, but we are also optimistic that this first-in-the-world surgery will provide an important new option for patients in the future.”
Revivicor, a regenerative medicine company based in Blacksburg, Virginia, made available the heart, according to the publication.
A total of 106,657 people are on the national transplant waiting list, and 17 people die each day waiting for an organ, according to organdonor.gov.
Art Caplan, a professor of bioethics at New York University, said he was a little apprehensive when he heard the news of Bennett’s transplant.
“I hope they’ve got the data to back up trying this now, based on their animal studies,” he said.
The United States has a “terrible” shortage of organs for transplants, he said. He believes engineering animal parts is a solution.
“The question is, can we get there with minimal harm to the first volunteers?” he asked.
Pig heart valves have been transplanted into humans for many years.
In October, surgeons successfully tested the transplant of a genetically modified pig kidney into a woman in New York who was brain-dead.
Caplan said it is too early to call the heart transplant a success. That label will come if Bennett has a good quality of life for months, he said. But it’s still possible that he could die.
Whatever the outcome, it’s important for researchers to learn something that can be applied to future transplants, he added.
He said there also should be an independent review of the data that went into the decision to do this first transplant.
The other ethics issue is around consent, he said. It should come from others besides the patient, who is very likely to agree to the surgery if he is facing death.
“Consent for the imminently dying is important to get … but it’s not enough,” he said, suggesting a research ethics committee weigh in.
“You want to have somebody else say, ‘Yes, we agree’ this isn’t a crazy, too risky thing to try.’ “
More than 40,000 transplants — a record — were done in 2021, according to the Organ Procurement and Transplantation Network.
