Yes, scientists and doctors have successfully transplanted genetically modified pig hearts into humans in experimental medical procedures. This type of transplant is called xenotransplantation, where organs from animals are used in humans.
One of the most well-known cases happened in the United States when surgeons transplanted a modified pig heart into a human patient as a last-resort treatment. The heart was able to beat and function inside the human body for some time.
However, there are still major challenges, such as immune rejection, infections, ethical concerns, and long-term survival. Scientists genetically modify pig organs to make them more compatible with humans.
This field is still experimental, but researchers believe it could help solve future organ shortage problems if proven safe and effective.
