Doctors did not give the exact cause of his death.

An American who became the first person in the world to have the heart of a genetically modified pig transplanted, died two months after the operation.

This is stated in a statement by the University of Maryland Medical Center.

“Last night, David Bennett, a 57-year-old patient with an incurable heart disease, who went down in history as the first person to whom the heart of a genetically modified pig was transplanted, died,” the medical center reported.

It is noted that Bennett’s health began to deteriorate a few days before March 8.

Doctors did not give the exact cause of his death.

As emphasized in the statement, for several weeks after the transplant, the heart worked without signs of rejection.
