Study Sheds Light on Death of Pig-Heart Transplant Patient

In January 2022, University of Maryland School of Medicine surgeon-scientists made history by successfully implanting a genetically modified pig heart into a fifty-seven-year-old patient in end-stage heart failure who did not qualify for a traditional heart transplant. It was considered an early success because the transplanted pig heart functioned well for several weeks without signs of rejection, but the patient ultimately died two months after the surgery. An autopsy determined the cause of death to be heart failure likely caused by variety of factors, including the use of intravenous immunoglobulin.
