The American becomes the world's first pig's heart

David Bennett, 57, is in good condition three days after the experimental procedure that lasted seven hours in Baltimore, doctors say.

This transplant was named the last hope of saving American lives, although it is still not clear what are the long - term chances of survival, the BBC writes.

“was either dead or doing this operation. I know it's a shot in the dark, but it was my last choice”, Bennett said one day before he underwent surgery.

Doctors at Maryland University Medical Center were granted special permission by the American health regulator for this procedure, reasoning that if such were not allowed, the husband would have died.

surgeon Bartley Griffith said this operation will bring the world a step closer to solving the problem of organ shortage. This crisis implies that 17 people die daily in the United States waiting for organ transplants, while more than 100,000 are reportedly on the waiting list.
