David Bennett lived two months with a pig heart before dying.
The heart was affected by porcine cytomegalovirus, which “maybe was the actor, or could be the actor, that set this whole thing off," Griffith said.Pigs raised to provide organs to humans are supposed to be virus-free, MIT Technology Review reported.
David Bennett received the genetically modified porcine heart on Jan. 7 after the Food and Drug Administration gave emergency authorization on New Year’s Eve. Before the transplant, Bennett had been hospitalized for six weeks with a life-threatening arrhythmia and had been connected to a heart-lung bypass machine.
Bennett’s transplant was a milestone in the field of xenotransplantation, the sourcing of animal organs to address the human organ supply crisis.
