An artificial heart is a device that replaces the heart. Artificial hearts are typically used to bridge the time to heart transplantation, or to permanently replace the heart in case heart transplantation is impossible. Although other similar inventions preceded it going back to the late 1940s, the first artificial heart to be successfully implanted in a human was the Jarvik-7, designed by Robert Jarvik and implemented in 1982. The first two patients to receive these hearts, Barney Clark and William Schroeder, survived 112 and 620 days beyond their surgeries, respectively.
An artificial heart is distinct from a ventricular assist device designed to support a failing heart. It is also distinct from a cardiopulmonary bypass machine, which is an external device used to provide the functions of both the heart and lungs and are only used for a few hours at a time, most commonly during cardiac surgery.

Famous quotes containing the words artificial and/or heart:
“We are becoming like cats, slyly parasitic, enjoying an indifferent domesticity. Nice and snug in “the social” our historic passions have withdrawn into the glow of an artificial cosiness, and our half-closed eyes now seek little other than the peaceful parade of television pictures.”
—Jean Baudrillard (b. 1929)
“They borrow words for thoughts they cannot feel,
That with a seeming heart their tongue may speak;
And in their show of life more dead they live
Than those that to the earth with many tears they give.”
—Jones Very (1831–1880)
