On this day 43 years ago, on December 2, 1982 (October 18, 1982 lunar calendar), the world's first artificial heart transplant was successfully performed. The world's first artificial heart transplant was performed by Dr. William Diveritz On December 2, 1982, 61-year-old Dr. Barney Clark became the first heart patient to be implanted with a permanent artificial heart. Clark is a retired dentist in the Seattle area. In December of that year, a surgical team led by Dr. William Diveritz of the University of Utah Medical Center in Salt Lake City completed a 7.5-hour artificial heart transplant operation for him. Before the operation, Clark was lying in a hospital bed for a long time due to heart failure and was facing the threat of death. Now Clark is supported by an artificial heart made of Javik No. 7 rubber metal. The Jarvik 7, named after its inventor, Dr. Robert Jarvik, replaced the heart's two ventricles, allowing blood to flow to the lungs and throughout the body. The Jarvik 7 kept the animal alive for months, but it was never used in humans. Soon after, the left part of the artificial heart began to fail, and after doctors replaced the left part of the artificial heart, doctors said Clark was beginning to recover gradually. The use of artificial hearts began in 1953, and it was not until 1965 that the American surgeon Michael Baker successfully implanted artificial hearts in animals for the first time to assist the operation of the ventricles. Barney Clark in the United States installed the first artificial heart
