'Historic': US surgeons successfully implant pig heart in human

US surgeons successfully implant genetically modified pig heart in human. It represents a major milestone for animal to human transplantation.

US surgeons have successfully implanted a heart from a genetically modified pig in a 57-year-old man, a medical first that could one day help solve the chronic shortage of organ donations.

The "historic" procedure took place Friday, the University of Maryland Medical School said in a statement on Monday. While the patient's prognosis is far from certain, it represents a major milestone for animal to human transplantation.
