The first robotic heart transplant was performed on a pig in 1985 - Apparently.
In a groundbreaking experiment, Dr. Robert Jarvik and his team at the University of Utah transplanted a mechanical artificial heart, the Jarvik-7, into a 15-month-old pig. The operation was a major breakthrough in the development of artificial hearts and paved the way for future research. The pig survived for 3 days with the artificial heart pumping blood before being euthanized. This experiment was a significant step towards creating functional artificial hearts for human transplantation, a goal that is still being pursued today.
