On January 7,David Bennett went into the operating room at the University of Maryland Medical Center for a surgical procedure never —(performe） before on a human.The 57-year-old Maryland resident had been hospitalized for months due to a life threatening disease.His heart was failing him and he needed a new one.
Bennett’ s condition left him—(responsive） to treatment and ineligible for the transplant list or an artificial heart pump.The physician-scientists at the center,however had another-also risky-option transplant a heart from a genetically-modified pig.
“It was either die or do this transplant,”Bennett had told surgeons a day before the operation. “I want to live. I know it's a shot in the dark,but it’s also my last— (choose).”
It took the medical team eight hours to finish the operation,making Bennett the first human to —(successful) receive a pig's heart.“It's working and it looks normal.We are thrilled,but we don't know what tomorrow will bring us.This has never been done before,”Barkley Griffith,—led the transplant team, told the New York Times.
While it's only been five days since the operation, the surgeons say that Bennett's new pig heart was, so far,functioning as expected and his body wasn't—( rejecte )the organ.They are still monitoring his condition closely.
“I think it's extremely exciting,” says Robert Montgomery, transplant surgeon and— (direct） of the NYU Langone Transplant Institute,was not involved in Bennett's operation.The result of the procedure was also personally —(meaning) for Montgomery,who received a heart transplant in 2018 due to a genetic disease that may also affect members of his family in the future. “It's still in the early days,but still the heart seems to be functioning.And that in and of—( it) is an extraordinary thing.Up to now most—( experiment) heart transplant procedures have been done between pigs and other animals.This is the first time that surgeons have taken it into a living human.”
