 The second person in the world to receive a genetically modified pig kidney has died. NPR's Rob Stein has more on the case. Doctors at NYU Langone Health in New York say Lisa Pisano died Sunday. The doctors say the 54-year-old New Jersey woman's death was unrelated to the pig kidney transplant in April. Doctors removed the kidney in May because the blood pressure medicine she was taking caused the organ to fail.
