Denton Cooley (born August 22, 1920, Houston, Texas, U.S.—died November 18, 2016, Houston) was an American surgeon and educator who was one of the most-renowned heart surgeons in the world, admired for his technical brilliance and his dexterity. He performed the first successful heart transplant in the United States and was also the first to implant an artificial heart in a human.
After graduating from the University of Texas in 1941, Cooley received an M.D. degree from Johns Hopkins University, Baltimore (1944). Following military service during World War II, he continued his training, now under British heart surgeon Russell Brock in London. In 1951 Cooley returned to Houston and joined Baylor College of Medicine, where he worked under Michael DeBakey. The two developed techniques to repair aortic aneurysms and to bypass arteriosclerotic blockages in the leg and neck. In addition, Cooley devised a method to reduce the amount of transfused blood needed when using a heart-lung machine. In 1962 Cooley founded the Texas Heart Institute at what was then St. Luke’s Episcopal Hospital. He and his team made improvements in techniques for implanting artificial valves, and he became known as an expert in surgery to correct congenital heart defects in infants and children. In 1975 he became a professor of clinical surgery at the University of Texas Medical School in Houston.
In 1969 Cooley ignited controversy, as well as a feud with his former mentor, DeBakey, when he implanted an artificial heart made of silicone—possibly the very one that DeBakey was developing—into a 47-year-old heart patient in hopes of keeping him alive long enough to find a donor. That artificial heart sustained the patient for 64 hours, but he died 32 hours after he received a donor heart.
Cooley was awarded (1967) the René Leriche Prize of the International Surgical Society. In 1984 he was honoured with the Presidential Medal of Freedom, and in 1998 he received the National Medal of Technology and Innovation, the highest honour in the U.S. for technological innovation.
