Tim Andrews, 68, survived a record 271 days with a transplanted pig kidney before successfully receiving a human donor kidney in a medical milestone.
The procedure, performed at Mass General Brigham, marks the longest dialysis-free survival for a porcine kidney xenotransplant and the first transition to a human organ.
Researchers believe xenotransplantation could become a viable bridge for the 100,000 people on the national transplant waiting list within the next five years.
