A Maryland man has lived for three days with a pig heart beating inside his chest.
The surgery, at the University of Maryland University of Maryland School of Medicine, marks the first time a gene-edited pig has been used as an organ donor.
Dave Bennett, 57, agreed to be the first to risk the experimental surgery, hoping it would give him a shot at making it home to his Maryland duplex and his beloved dog, Lucky.
“This is nothing short of a miracle,” his son David said Sunday, two days after his father's life-extending surgery. “That’s what my dad needed, and that’s what I feel like he got.”
In the nine-hour surgery, doctors replaced his heart with one from a 1-year-old, 240-pound pig gene-edited and bred specifically for this purpose.
Bennett is breathing on his own without a ventilator, though he remains on an ECMO machine that does about half the work of pumping blood throughout his body. Doctors plan to slowly wean him off.
