O. H. Frazier

Oscar Howard Frazier Jr. was born and grew up in Stephenville, Texas, in a Methodist household. Both his parents were teachers and his grandfather nicknamed him "Bud" after a distant cousin who was killed in a West Texas saloon shootout at the turn of the nineteenth century. he was initially destined for a career in football, Interviewed for medicine on the 4 July, he won a place at Baylor College of Medicine, atypically on the ability to answer a question on history. ==Medical education==

As a medical student at BCM in 1964, he assisted in experimental total artificial hearts (TAH) research, which placed him under the mentorship of Michael E. DeBakey, Domingo Liotta and Denton A. Cooley, In 1966, at the age of 25, while still a medical student of DeBakey, who he described as a “tough taskmaster”, an experience with a teenager who had just had an aortic valve repair, left a lasting impression on him. Frazier was required to manually massage the teenager's heart following a cardiac arrest. He has since repeatedly recounted "that as long as I was massaging that kid's heart, he would wake up... I thought then, and I've often returned to this: If my hand can keep this kid alive, why couldn't we make a device to do the same?" It was this incident and the experience with DeBakey's research that instilled his interest in cardiac surgery and MCS's. before then completing his residency at Baylor Affiliated Hospitals in 1968. ==Vietnam==

Frazier served in the United States Army from 1968 to 1970 and distinguished himself as a flight surgeon in the U.S. Army 48th Assault Helicopter Company in the Vietnam War. Once, he was shot down and on return to the States, has described how demoralised he felt about what men were capable of during war. For his achievements, he received three medals, the Combat Flight Medal, Vietnamese Navy Medal, and the Vietnamese Distinguished Service Medal. ==Surgical career==

After Vietnam, Frazier returned as a surgical resident to BCM. When funding for TAH research was restored in January 1991, Frazier became involved in further animal experiments. His innovations in the surgical treatment of severe heart failure, heart transplantation and MCS to be used either to substitute for or to assist the pumping action of the human heart led to the THI gaining a reputation as a global leader of transplantation and MCS programmes. Frazier performed more than 1,300 heart transplants and implanted 1,000 LVADs, exceeding the performance of any other contemporary surgeon in the world during his career. Successful implantation of a continuous flow device In March 2011, Craig Lewis was suffering from amyloidosis and not eligible for heart transplant due to the severity and extent of the disease, affecting also his kidney and liver. Unsuitable for a heart transplant, temporary mechanical TAH or LVAD, his small diseased heart was replaced with a continuous flow device, a pair of HeartMate II pumps, an apparatus of two pumps embraced together, following six years of research on more than fifty calves at the Texas Institute. He awoke from a coma and spent the last five weeks of his life interacting with his family. During the following year, Frazier and his colleague William Cohn engaged with the public and professionals on their experiences. Their TEDMED talk introduced them to Daniel Timms, who was driven to find a technological resolution and whose father had died of heart failure. Timms had an idea and sought out Frazier and Cohn in the States. The surgeons became interested, particularly with the idea that Timms's device had the potential to be a small size. Trialed in numerous calves between 2013 and 2016, some were able to run a treadmill after implantation. ==Appointments==

Frazier has been Professor of surgery at the University of Texas Health Science Center in Houston, Clinical professor of surgery at the University of Texas M.D. Anderson Cancer Center, co-director of Center for Preclinical Surgical & Interventional Research at the Texas Heart Institute, and Tenured professor at Baylor College of Medicine. He has served on the editorial boards of several medical journals, including Circulation, the Journal of the American Heart Association, and The Journal of Heart and Lung Transplantation. ==Awards and honors==

Medical honors include the Living Legend Award from the World Society of Cardiothoracic Surgeons, BCM Distinguished Alumnus Award, University of Texas Distinguished Alumnus Award, the Gift to Mankind Award from the American Organ Transplant Association, the Distinguished Surgeon Award from the Houston Surgical Society, Honored Physician Award from the American Heart Association Guild, the Ray C. Fish Award for Scientific Achievement from the Texas Heart Institute and the Denton A. Cooley Cardiovascular Surgical Society International Recognition Award. In 2014, Dr. Frazier was presented with the Lifetime Achievement and Distinguished Faculty Award from the Michael E. DeBakey department of surgery at BCM. Frazier's award presentation preceded keynote speaker, former Vice President Dick Cheney, whose life was extended by the technology Frazier helped to develop. Since 2014, the International Society of Heart and Lung Transplantation (ISHLT) has awarded the "O.H. Frazier Award" in MCS Translational Research sponsored by Medtronic. In 2018, the ISHLT awarded Frazier with their ISHLT Lifetime Achievement Award in acknowledgement of his work on severe heart failure, heart transplantation and mechanical circulatory support. In 2021, the American Association for Thoracic Surgery (AATS) distinctly honored Frazier with the Scientific Achievement Award, the highest recognition the Association can bestow. Previous recipients include Dr. Michael DeBakey, Dr. Denton Cooley, and Sir Magdi Yacoub. Published in 2018, a book entitled Ticker, recounts the story of Frazier's task to construct a sustainable totally implantable artificial heart. The author describes Frazier sharing traits with pioneers in other fields and how for over half a century been driven by the desire to save lives. In response, reviewers have either been intrigued to what drives Frazier or have debated the ethics surrounding TAHs and LVADs. == Controversies ==

In 2018, ProPublica and the Houston Chronicle published an investigation into Frazier, claiming that he had been "accused of violating federal research rules and skirting ethical guidelines, putting his quest to make medical history ahead of the needs of some patients." Frazier subsequently sued the authors of the investigation, as well as ProPublica and the Houston Chronicle, for defamation, claiming that articles written about him had contained misleading statements "calculated to falsely portray Dr. Frazier as an inhumane physician." The back-and-forth legal battle came to a close in 2024, when a Texas state appeals court ordered the lawsuit dismissed. ==Personal and family==

Frazier has previously led Sunday school and collects rare books. He is married to Rachel, and they have two children, Todd, who graduated from the Juilliard School of Music and became a composer, and Allison, a writer. ==Selected publications==
