Professor On Topaz received the MD degree in 1979 from the Sackler School of Medicine, Tel-Aviv University and completed residencies in Internal Medicine and Cardiology at the Beilinson and Meir hospitals, Israel. He is a graduate of 3 clinical and research US fellowships including Cardiovascular Pathology at the University of Minnesota [1983-1984], adult Cardiology at the University of Miami [1986-1989] and Interventional Cardiology at the Medical College of Virginia[1989-1990]. Following this extensive training he became an Assistant Professor at Case Western Reserve University and then at the University of Minnesota. In 1993 he joined the division of cardiology, Medical College of Virginia/Virginia Commonwealth University in Richmond, Virginia with a rank of Associate Professor serving as the director of interventional cardiology of the McGuire Veterans Affairs Medical Center . He was a member of the admissions committee of this school of medicine for 11 years . In 2001 he received the rank of Professor of Medicine and in 2002 received as well as a rank of Professor of Pathology. In 2010 he was nominated the chief of the division of Cardiology of Charles George Veterans Affairs Medical Center in Asheville, North Carolina with a rank of Professor of Medicine at the Duke University School of Medicine. Professor Topaz's main clinical specialty is percutaneous interventions for complex lesion subsets in challenging coronary and peripheral vascular targets. He specializes in treatment of patients with critical lesions in the presence of depressed LVEF, severe left main disease, old saphenous vein grafts, chronic total occlusions, stent thrombosis and heart transplant allograft disease . He has special interest in revascularization of severe renal artery stenosis and severe subclavian artery occlusions. Professor Topaz is the inventor of several percutaneous revascularization techniques with advanced debulking technology for plaque extraction and thrombus removal. He is also a national and international proctor of FDA approved plaque debulking and thrombectomy devices such as laser and rheolytic thrombectomy. Professor Topaz's clinical investigations and basic research focus on cardiovascular thrombus including pathology and exploration and development of dedicated revascularization strategies for management of thrombus and its constituents during various phases of coronary and peripheral ischemic syndromes . He has gained global recognition for contribution to the understanding and the treatment of thrombotic lesions in acute ischemic/ thrombotic coronary and peripheral syndromes and authored the chapter on The thrombus containing lesion for several editions of the Textbook of Interventional Cardiology, edited by Topol and Teirstein and published by Elsevier. Professor Topaz is a world authority on cardiovascular lasers whereby he pioneered the contemporary coronary lasing techniques and introduced the utilization of laser revascularization in acute myocardial infarction. In addition, he developed laser application for treatment of congenital heart conditions such as pulmonic atresia. Professor Topaz conducts basic research on the effects of laser irradiation on cardiac and vascular bio-tissue with special focus on the interaction of laser energy with thrombus and platelets. He discovered the unique phenomena of laser- induced enhancement of thrombolytic agents activity and laser induced suppression of platelet aggregation. Clinically, he investigates the therapeutic outcomes of various cardiovascular lasers. Professor Topaz is a recognized researcher and scholar of cardiovascular pathology and vascular anatomy. In 2010 he discovered in several patients the... See less
