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 same Maryland team last year performed the world’s first transplant of a genetically modified pig heart into another dying man, David Bennett, who survived just two months.“Nobody knows from this point forward. At least now I have hope and I have a chance,” Faucette, from Frederick, Maryland, said in a video recorded by the hospital before the operation.
Attempts at animal-to-human organ transplants have failed for decades, as people’s immune systems immediately destroyed the foreign tissue. Now scientists are trying again using pigs genetically modified to make their organs more humanlike. It took over 300 pages of documents filed with FDA, but the Maryland researchers made their case that they’d learned enough from their first attempt last year – even though that patient died for reasons that aren’t fully understood – that it made sense to try again.
