The first person to receive a heart transplant from a pig has died, two months after the groundbreaking experiment, the Maryland hospital that performed the surgery announced Wednesday. David Bennett, 57, died Tuesday at the University of Maryland Medical Center.
Before the transplant, Bennett had been hospitalized for six weeks with a life-threatening arrhythmia and had been connected to a heart-lung bypass machine. He was in end-stage heart failure and didn't qualify for a traditional heart transplant. He died two months later.
The transplanted pig heart functioned well for several weeks and displayed none of the typical signs of rejection by the patient's body, even when it was carefully examined during an autopsy, according to the analysis in the paper.
The first person in the world to get a heart transplant from a genetically-modified pig has died. David Bennett, who had terminal heart disease, survived for two months following the surgery in the US.
The world's first porcine-to-human heart transplantation was performed at the University of Maryland School of Medicine (Baltimore, MD, USA), where a genetically modified pig heart was successfully transplanted into a 57-year-old man in the end stage of heart disease.
But primates are hard to care for, are prone to infection, and their bodies don't always react the same as humans. “In the last few years, we've seen survivals of pig hearts in nonhuman primates going six to nine months. That's huge and that's really a big advance,” Sykes said.
In 2016, they reported that pig hearts could remain healthy for more than 2 years when transplanted into a baboon's abdomen, and have since done transplants into baboons' chests, where the hearts sustain life. In recent experiments, baboons relying on Revivicor's pig hearts survived up to 9 months, Mohiuddin says.
The longest surviving heart transplant patient is Harold Sokyrka (Canada, b. 16 January 1952), who has lived for 34 years and 359 days after receiving his transplant on 3 June 1986, in London, Ontario, Canada as verified on 28 May 2021.
Because those busted capillaries fed the heart with oxygen, cardiac muscle cells began to die in their absence. On day 60, Griffith's team withdrew life support because Bennett's heart had been irreversibly damaged.
The Pig That Called for Help is a drama-documentary recounting how a pet pig summoned medical attention for a dying woman. Heart patient Jo Ann Altsman was alone when she collapsed while holidaying in Pennsylvania.
A pig's heart is anatomically similar to a human, they pose less of a disease risk and the animals grow quickly, making them an excellent substitute. Crucially, by modifying a pig's genetics, Mohuiddin was able to render the transplanted hearts invisible to the baboon's immune system.
The heart acts as a synchronizing force within the body, a key carrier of emotional information as well as other personality keys. Sensitive transplant patients may evidence personality changes that parallel the experiences, likes, dislikes, and temperament of their donors.

The world record: 56 years
On average, a transplanted kidney from a deceased donor lasts about 15 years.
Though a successful heart transplant was a major medical milestone, in the early days, patients with these new hearts didn't live that long. Now many people live for decades, with a median survival of 14 years, according to Dr.
The patient lived for 61 days. Researchers have been working on this new pig-to-human transplantation technique for over 30 years. If successful, harvesting hearts from genetically modified pigs, whose genes have been altered so that they can be safely transplanted to humans, may one day be a reality.
Fiona Coote was Australia's youngest heart transplant recipient when she underwent surgery at the age of 14 on 8 April 1984.
While transplanted organs can last the rest of your life, many don't. Some of the reasons may be beyond your control: low-grade inflammation from the transplant could wear on the organ, or a persisting disease or condition could do to the new organ what it did to the previous one.
Setting complications aside, Newark Beth Israel heart transplant enables most patients to return to a normal life— the majority of patients can resume all normal daily activities and live with minimal to no symptoms. Heart transplant patients can take control of their recovery and heart transplant life expectancy.
Out of 100 patients, 72 are alive five years after a heart transplant. How long does a transplanted heart last? Longer-term survival is increasing and there are several patients in the UK who have survived beyond 30 years.
Not so, said Church, who points out that the cost of a heart transplant in the US is around $1.66 million, according to the most recent estimates, while pig transplants, judging solely on the cost of the pig heart transplants for baboons, are a comparative steal at just $500,000.
A team at NYU Langone successfully completed two xenotransplants involving pig hearts and deceased humans in what is the latest step in a research protocol to increase the available supply of donor organs.
Pig hearts beat for three days inside the chests of two brain-dead patients who were kept alive using ventilators. The feat helps researchers prepare for future clinical trials of pig-to-human transplants, surgeons at the NYU Langone Health in New York City announced at a news conference on July 12.
