He is board certified in cardiovascular diseases and interventional cardiology, and is a practicing interventional cardiologist. His clinical interests and expertise are in complex PCI with an emphasis in CTOPCI. Dr. Marso is extremely active in clinical research, with research interests in evaluating the cardiovascular safety and efficacy of therapies to treat diabetes mellitus. He is involved in several ongoing large cardiovascular outcome trials. Dr. Marso also has a research interest in evaluating the outcomes following PCI using large national databases. He has served on numerous professional leadership committees for entities such as the American Heart Association, the American College of Cardiology and the state of Missouri, among others. Dr. Marso has published more than 130 peer-reviewed manuscripts, edited four textbooks, mentored more than20 Interventional Cardiology fellows and is a frequent invited lecturer on the topics of PCI and diabetes and cardiovascular disease. He serves on the editorial advisory board for Cardiology Today Intervention, and is a fellow of the American College of Cardiology, Council of Arteriosclerosis, Thrombosis and Vascular Biology and the American Heart Association. Dr. Marso earned his medical degree at the University of Kansas School of Medicine and trained in Internal Medicine at the University of Virginia.
