This first transplant by the team of surgeons at the University of Maryland Medical Center is the culmination of an exceptional mobilization of research teams. The transplanted heart comes from a pig farm specifically designed for human transplants. These pigs are bred under strictly sterile conditions over several generations. They are also genetically modified using a genome-editing technique, the only way to avoid inevitable rejection. The 57-year-old patient was ineligible for organ donation, and all therapeutic solutions had been exhausted.
