This is the first total artificial heart implanted in a human body. It was developed by Domingo Liotta and implanted by surgeon Denton Cooley (1920-2016) on April 4, 1969, at St. Luke's Episcopal Hospital in Houston. The recipient, Haskell Karp, lived for sixty-four hours with the artificial heart pumping oxygenated blood through his body until a human heart was available for transplant.
Although Karp died soon after receiving a real heart, and some criticized the surgery as unethical because it was without formal review by the medical community, the procedure demonstrated the viability of artificial hearts as a bridge to transplant in cardiac patients.
