Winters Family Distinguished Centennial Chair in Cardiovascular Education in honor of Christopher, William and Scott Winters, DeBakey Heart & Vascular Center
Professor of Cardiology, Institute for Academic Medicine
Full Member, Research Institute
Weill Cornell Medical College
Dr. Quiñones joined the faculty of Baylor College of Medicine at Houston Methodist Hospital in 1977 after serving two years in the military as Chief of Cardiology at Moncrief Army Hospital in Fort Jackson, South Carolina. He was made full professor in 1987 and retained this position until 2005, when he became Chair of the Department of Cardiology at Houston Methodist Hospital and Professor of Medicine at Weill Cornell Medical College.
He served as director of the Echocardiography Laboratory at Houston Methodist from 1977 to 2002. From 2003 to 2008, he served as medical director of the Houston Methodist DeBakey Heart & Vascular Center. Dr. Quiñones has served on the Board of Directors of the American Society of Echocardiography and the American College of Cardiology as well as on the editorial board of several peer-reviewed journals including Circulation and the Journal of the American College of Cardiology. In addition, he has served on the Executive Board of the Interamerican Society of Cardiology.
Dr. Quiñones has authored or co-authored over 200 manuscripts in peer review journals. He has served as a member of several writing groups in echocardiography and chaired the writing group for the ACC/AHA Clinical Competence Statement on Echocardiography. In 2012, Dr. Quiñones received a Master of the American College of Cardiology Award and a Lifetime Achievement Award from the American Society of Echocardiography. Dr. Quiñones is currently President of the Houston Chapter of the American Heart Association.
Echocardiography; cardiac function
Dr. Quiñones has been one of the pioneers in the field of cardiac ultrasound over the past 40 years, and has developed multiple methods for the evaluation of cardiac and valvular function at rest and during stress. His laboratory made important contributions in developing echocardiographic methods to measure left ventricular volumes and ejection fraction, cardiac output, regurgitant fractions in mitral and aortic insufficiency, and valve area in aortic stenosis. Dr. Quiñones played a pivotal role in the development of stress echocardiography as a clinical tool for the evaluation of coronary artery disease, and validated the technique against coronary angiography and nuclear stress imaging. He and his colleagues have also developed newer methods to evaluate diastolic function and estimate left ventricular filling pressures by echocardiography.
