For more than 30 years, Dr. O. H. Frazier has been a pioneer in the treatment of severe heart failure and in the fields of heart transplantation and artificial devices that may be used either to substitute for or assist the pumping action of the human heart. As a result of his work, he become one of the top transplantation and mechanical circulatory support surgeons in the world. Dr. Frazier performed over 1,200 heart transplants and implanted more than 900 left ventricular assist devices, more than any other surgeon in the world.

Dr. Frazier’s interest in mechanical circulatory support began in 1969, when, as a student at Baylor College of Medicine, he wrote a research paper about the experimental total artificial heart, which was first implanted in 1969 by Dr. Denton Cooley. Throughout the 1970s and 1980s, Dr. Frazier continued experimental work toward developing an implantable left ventricular assist device (LVAD) to aid the failing heart.In 2011, Dr. Frazier implanted the first successful continuous-flow total artificial heart using two second generation HeartMate II LVADs to replace a patient’s failing heart.
