A man with terminal heart disease is responding well three days after being given a genetically modified pig heart in a first-of-its-kind surgery, his doctors reported on Monday.
The surgery, performed by a team at the University of Maryland Medicine in the United States, is among the first to demonstrate the feasibility of a pig-to-human heart transplant, a field made possible by new gene editing tools.
If proven successful, scientists hope pig organs could help alleviate shortages of donor organs.
For David Bennett, a 57-year-old from Maryland, the heart transplant was his last option.
