Pig-to-human heart transplants are currently limited by the supply of pigs and regulatory hurdles. As scientists look ahead, they hope to learn more about the genetic modifications needed in transplanted animal organs and continue clinical trials. On December 2, 1982, Barney Clark became the first individual to receive the Jarvik-7 artificial heart in an operation performed by Dr. “We have gained invaluable insights learning that the genetically modified pig heart can function well within the human body while the immune system is adequately suppressed,” said Muhammad Mohiuddin, one of the surgeons who performed the procedure. The heart functioned well without rejection for about two months, but his condition began deteriorating and he passed away on March 8. The organ had 10 genetic modifications to ensure Bennett’s body did not reject the organ, and the modifications also ensured that a heart from a 400 kg animal remained human-sized. 6, 1992 12 AM PT ASSOCIATED PRESS SALT LAKE CITY For 112 days, as a plastic heart pumped in his chest, Barney Clark. In January 2022, surgeons at the University of Maryland Medical Center transplanted a heart from a genetically modified pig into 57-year-old David Bennett. World & Nation Widow Wishes They Had Talked More By PEG McENTEE Dec. health care system must rethink which hospitals should do heart transplants.Ĭiting studies from Cardiology Research and other scientific publications, Healthmatch compiled a timeline of the development of an alternative human heart.īSIP/Universal Images Group via Getty Images Barney Clark, a 61 year old dentist from Seattle suffering from extreme congestive heart failure so severe that a normal heart transplant was not an option. “The bar for patient safety, quality of care, and survival needs to be set pretty high,” said senior study investigator and cardiac surgeon John Conte. Patients who receive their transplants at high-volume facilities have a better survival rate and fewer complications. In 2008, surgeons at Johns Hopkins Medicine recommended that for a hospital to be named a high-volume facility, it should perform 14 procedures a year-an increase from the earlier benchmark of 10 procedures a year. Their goal is to provide artificial hearts as a temporary option so that patients who would not otherwise survive on a temporary pump have more time until a donor heart can be found. The challenge of finding a donor heart has long motivated scientists to develop an artificial heart. A 2021 study published in the Journal of the American Heart Association found that over the past decade, the percentage of organs accepted for transplant has not increased proportionally to the number of donor hearts offered for transplant. Since 1982, more than 350 patients have used the Jarvik 7 heart, and it remains in use today.About 2,000 hearts are available each year for transplantation, but more than 3,000 people are on the heart transplant list. Soon after, it became a more widely used temporary total artificial heart, bridging patients to transplant. The University of Utah achieved its research and educational goals with the success of that first seven-hour surgery and there were several more implantations of the Jarvik 7 heart over the next year. All medically significant events in the post-operative course were reported, successes and setbacks alike.” ![]() “Enormous public interest developed, and hundreds of reporters converged on Salt Lake City to cover the story, and the University began to give them daily briefings, which were completely uncensored. ![]() “The news about Barney Clark stunned the doctors by making headlines around the world”, Dr. Others equated it with Frankenstein-like aspects, raising bioethical questions and concerns. In 1982, such a drastic surgical procedure was akin to the significance of putting a man on the moon or seeing a different planet for the first time.
