Surgeons perform first successful transplant of pig heart to human patient

A man is doing well after the first successful transplant of a pig heart into a human body, possibly opening a new path for those facing an overburdened donor system, according to the University of Maryland, NBC News reports.

The Food and Drug Administration on New Year’s Eve gave emergency authorization for David Bennett, 57, to receive a genetically modified pig heart, the University of Maryland Medical Center said. Bennett, who had been deemed ineligible for a conventional heart transplant, had been hospitalized for six weeks with a life-threatening arrhythmia and was connected to a heart-lung bypass machine.

Dr. Bartley Griffith, the operating physician, on Monday described the transplant as a "breakthrough surgery."

"There are simply not enough donor human hearts available to meet the long list of potential recipients," Griffith said in a statement. "We are proceeding cautiously, but we are also optimistic that this first-in-the-world surgery will provide an important new option for patients in the future."

Griffith and Dr. Muhammad M. Mohiuddin, professor of surgery at the University of Maryland School of Medicine, spent five years perfecting techniques for transplanting pig hearts into nonhuman recipients.

Bennett will continue to be monitored in the coming weeks but has appeared to be doing fine in the three days since surgery.
