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:
“For, as it is dislocation and detachment from the life of God, that makes things ugly, the poet, who re-attaches things to nature and the Whole,—re-attaching even artificial things, and violations of nature, to nature, by a deeper insight,—disposes very easily of the most disagreeable facts.”
—Ralph Waldo Emerson (1803–1882)
“Though I knit my brow,
my gaze is fixed
longingly
anyway.
Though I check my tongue,
this tortured face of mine
dissolves in a smile.
Though I drive my heart to hardness,
my body bears
the gooseflesh
of desire.
When I see that man,
how on earth
can my anger
survive?”
—Amaru (c. seventh century A.D.)
