The transplant was considered the last hope of saving Mr Bennett's
life, though it is not yet clear what his long-term chances of
survival are.
"It was either die or do this transplant," Mr Bennett explained a day
before the surgery.
"I know it's a shot in the dark, but it's my last choice," he said.

In October 2021, surgeons in New York announced that they had
successfully transplanted a pig's kidney into a person. At the time,
the operation was the most advanced experiment in the field so far.
However, the recipient on that occasion was brain dead with no hope of
recovery.
Mr Bennett, however, is hoping his transplant will allow him to
continue with his life. He was bedridden for six weeks leading up to
the surgery, and attached to a machine which kept him alive after he
was diagnosed with terminal heart disease.
"The pig used in the transplant had been genetically modified to knock
out several genes that would have led to the organ being rejected by
Mr Bennett's body, the AFP news agency reports."
