Surgeons have transplanted a pig’s heart into a dying man in a bid to prolong his life – only the second patient to ever undergo such an experimental feat. Two days later, the man was cracking jokes and able to sit in a chair, Maryland doctors said Friday.
The 58-year-old Navy veteran was facing near-certain death from heart failure but other health problems meant he wasn’t eligible for a traditional heart transplant, according to doctors at University of Maryland Medicine.
