Heart transplant genetically modified

January 11, 2022
David Bennett (57) receives a genetically modified pig heart transplant — the first transplant of its kind.

It was either die or do this transplant. I want to live. I know it’s a shot in the dark, but it’s my last choice.

57-year-old David Bennett, a handyman, who received the heart of a genetically modified pig – the first transplant of its kind.
  • Doctors call this event a "watershed" moment.
  • Bennett suffered from heart failure and an irregular heartbeat. He previously received valves from a pig heart.
  • This total heart transplant came from a genetically modified pig heart. Sugar – which can trigger organ rejection – was removed from the pig's cells by means of gene-editing.
  • Many Americans (and people around the world) face the need for organ transplants but confront low supply.
  • Why It Matters: The lead doctor for this animal-to-human transplant program said it best: “If this works, there will be an endless supply of these organs for patients who are suffering.”
