US man who got 1st pig heart transplant dies after 2 months KPRC2
In this photo provided by the University of Maryland School of Medicine, David Bennett Jr., right, stands next to his father's hospital bed in Baltimore, Md., on Jan. 12, 2022, five days after doctors transplanted a pig heart into Bennett Sr., in a last-ditch effort to save his life. Bennett, the first person to receive a heart transplant from a pig died Tuesday, March 8, at the University of Maryland Medical Center, two months after the groundbreaking experiment.
Bennett's son praised the hospital for offering the last-ditch experiment, saying the family hoped it would help further efforts to end the organ shortage. Prior attempts at such transplants -- or xenotransplantation -- have failed largely because patients’ bodies rapidly rejected the animal organ. This time, the Maryland surgeons used a heart from a gene-edited pig: Scientists had modified the animal to remove pig genes that trigger the hyper-fast rejection and add human genes to help the body accept the organ.
The need for another source of organs is huge. More than 41,000 transplants were performed in the U.S. last year, a record -- including about 3,800 heart transplants. But more than 106,000 people remain on the national waiting list, thousands die every year before getting an organ and thousands more never even get added to the list, considered too much of a long shot.
