The 61-year-old retired dentist was in an advanced stage of cardiomyopathy, a progressive weakening of the heart muscle, when he became [the first recipient of a permanent artificial heart](http://www.nytimes.com/1983/03/24/obituaries/barney-clark-dies-on-112th-day-with-permanent-artificial-heart.html?module=Search&mabReward=relbias%3Ar%2C%7B%221%22%3A%22RI%3A7%22%7D) on this day, Dec. 2, in 1982. Heart transplants were already being done to prolong lives, but in a limited, last-resort way. Surgeons accomplished the first human-to-human transplant in South Africa in 1967, when [a man with severe heart damage received the heart of a 25-year-old woman who had died in a car crash](http://hearttransplant.com/history.html). He survived 18 days. In 1977, after new immunosuppressant drugs dramatically increased the odds of survival, the first recipient of a heart transplant at Columbia University’s Medical Center — one of only three institutions in the country performing the surgery at the time — survived 14 months. But Clark was 11 years too old to be a candidate for a heart transplant, according to the criteria U.S. surgeons had by then agreed on. His only shot at survival was Dr. Robert Jarvik’s [pneumatically-powered heart](http://content.time.com/time/subscriber/article/0,33009,923159-1,00.html). The Jarvik 7, as it was called, comprised two plastic pumps powered by compressed air, which required the patient to be hooked up at all times to [a rolling console the size and weight of a refrigerator.](http://www.texasheart.org/Research/Devices/j7tah.cfm) The artificial heart could pump blood through the body at 40 to 120 pulses per minute, but it replaced the telltale heartbeat with a soft clicking sound followed by a whoosh. Clark knew what he was in for: before agreeing to the operation, he first toured a facility where Jarvik’s hearts were keeping several sheep and calves alive, including [a calf named Tennyson who set the survival record of 268 days](http://content.time.com/time/subscriber/article/0,33009,923159-1,00.html), according to TIME. He met the requirements for the surgery by having a fatal heart condition, with no other treatment alternatives, as well as a strong will to live. By the time of the surgery, he was nearly dead already: [his heart was pumping a liter of blood per minute, or a fifth the normal rate.](http://content.time.com/time/subscriber/article/0,33009,923159-1,00.html) The surgery was considered a success, since Clark went on to live another 112 days. A surgeon told TIME that [his color had changed](http://content.time.com/time/subscriber/article/0,33009,923159-3,00.html), from blue to pink, after more oxygen infused his blood. There were hitches, however. A week after the surgery, he suffered a series of seizures his doctors blamed on an imbalance of fluids and salts. Following the seizures, [he was often disoriented](http://content.time.com/time/subscriber/article/0,33009,951883,00.html), and sometimes believed he was still a dentist in Seattle. He never left the hospital after his transplant, and ultimately died of “circulatory collapse and secondary multi-organ system failure” triggered by an infection that was likely the result of a blood transfusion, [according to his obituary](http://www.nytimes.com/1983/03/24/obituaries/barney-clark-dies-on-112th-day-with-permanent-artificial-heart.html?module=Search&mabReward=relbias%3Ar%2C%7B%221%22%3A%22RI%3A7%22%7D) in the New York _Times._ Later recipients fared somewhat better with the Jarvik 7\. [William Schroeder lived a record 620 days with one](http://www.nytimes.com/1986/08/10/us/hero-medicine-schroeder-longest-user-jarvik-device-helped-prove-hearts-can-be.html?pagewanted=1), although his quality of life was poor after he suffered serious strokes within the first three weeks. Another recipient, Leif Stenberg, made remarkable progress with his new heart, and [lived 229 days before suffering a fatal stroke](http://www.nytimes.com/1985/11/22/us/leif-stenberg-swedish-heart-recipient-dies.html). Stenberg’s renewed vigor was a triumph fraught with unexpected philosophical considerations. Long suspected of being a [powerful Swedish crime boss](http://content.time.com/time/subscriber/article/0,33009,966873,00.html), he was never convicted of any crime, partly because his health problems delayed a trial on charges of tax evasion. But the transplant led to a new delay, since Swedish law defined death as the moment when one’s heart stopped beating. Stenberg’s attorneys, therefore, [argued that he should not have to stand trial](http://content.time.com/time/subscriber/article/0,33009,966873,00.html), since he was already dead. **_Read the full report on Barney Clark’s operation from 1982, here in the TIME Vault_**: [Living on Borrowed Time](http://time.com/vault/issue/1982-12-13/page/108/) ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3605433/artificial-heart/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3605433/artificial-heart/"},"headline":"Plastic and Permanent: The Artificial Heart's Debut","datePublished":"2014-12-02T15:30:30.000Z","dateModified":"2026-02-22T02:22:28.671Z","description":"Dec. 2, 1982: Doctors implant the first permanent artificial heart in a human, Barney Clark, who lives 112 days with it","url":"https://time.com/3605433/artificial-heart/","keywords":["health","medicine","Science topic","heart","transplant"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blte5093d8469f3eca4/69876af1e53aba28d44d6230/heart.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Jennifer Latson","jobTitle":null,"url":"https://time.com/author/jennifer-latson/"}],"articleSection":"History","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blte5093d8469f3eca4/69876af1e53aba28d44d6230/heart.jpeg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"First Artificial Heart Implantation","caption":"First Artificial Heart Implantation","creditText":"Ravell Call—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/history/","name":"History"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/health/","name":"health"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3605433/artificial-heart/","name":"Plastic and Permanent: The Artificial Heart's Debut"}}]}] ```
