The very first artificial heart was implanted in an animal – in this case, a dog- by Soviet scientist Vladimir Demikhov, in 1937.
On December 2nd, 1982, Kolff implanted the Jarvik 7 artificial heart into Barney Clark, a dentist from Seattle who was suffering from severe heart failure. Even though the surgery was a success, the patient survived only for 112 days, that too having bleeding and acute medical conditions.
Today, the modern version of the Jarvik 7 is known as the SynCardia Temporary Total Artificial Heart. It has been implanted in more than 1,350 people as a bridge to transplantation.
