Patent Foramen Ovale Closure for Stroke, Myocardial Infarction, Peripheral Embolism, Migraine, and Hypoxemia

Dr. M. Khalid Mojadidi is an Invasive Cardiologist and Assistant Professor of Medicine at Virginia Commonwealth University. His clinical concentration includes invasive and noninvasive cardiology, echocardiography, and nuclear cardiology. His research interests include PFO and related clinical pathologies. Since early in his career, he has published extensively on different aspects of percutaneous PFO closure for numerous medical conditions. Bernhard Meier has served from 1992 to his retirement in 2015 as full Professor of Cardiology and Chairman of the Department of Cardiology at the Swiss Cardiovascular Center Bern of the University of Bern, Switzerland. Since 2016, he served as a Senior Consultant. He has personally performed thousands of coronary angioplasties, starting with assisting on the world’s first case in 1977, and other catheter-based cardiac procedures. He implanted the world’s first dedicated PFO occluder in 1997. Dr. Jonathan M. Tobis is the Director of Interventional Cardiology Research at UCLA and Clinical Professor of Medicine in Cardiology at the University of California, Los Angeles. He performed the world’s first digital left ventricular and coronary angiograms and contributed to the advancements of intravascular ultrasound early in his career. His recent work is devoted to understanding the role of PFO closure in relation to several medical conditions including stroke and migraine. He was voted one of the 10 Most Highly Regarded Heart Doctors in the United States.
