Dr. Barry H. Trachtenberg is a cardiologist specializing in heart failure and cardiac transplantation. He is board certified in internal medicine, cardiovascular disease, nuclear cardiology, echocardiography and advanced heart failure and transplant. He received his B.S. degree from the University of Pennsylvania and attended medical school at the University of Texas-San Antonio. Dr. Trachtenberg, a native Houstonian, completed his residency in internal medicine at the Baylor College of Medicine prior to his cardiology training at the University of Miami School of Medicine. His clinical experience includes heart failure and heart transplantation, mechanical support pumps, and cardio-oncology. He performs diagnostic catheterizations (including radial artery approach) and endomyocardial biopsies. He has contributed to many publications related to advanced heart failure, cardiac transplantation, regenerative therapies, and ventricular assist devices. Dr. Trachtenberg is a member of the American Heart Association, the International Society for Heart and Lung Transplantation Association, Heart Failure Society of America, and the International CardiOncology Society of North America.
