Originally from Wisconsin, Dr. Czarny attended the University of Wisconsin where he majored in molecular biology.  After medical school at the Johns Hopkins University School of Medicine, he completed an internal medicine residency at the Brigham and Women’s Hospital in Boston followed by cardiovascular disease and interventional cardiology fellowships at Johns Hopkins.  Currently, he is a faculty member in interventional cardiology and performs heart cathetheterizations and coronary artery stenting for patients with stable coronary artery disease (CAD) and myocardial infarctions ("heart attacks") at both the Johns Hopkins Hospital and the Johns Hopkins Bayview Medical Center.  In addition, he is the structural and peripheral interventions fellow at Johns Hopkins, where he focuses on the use of minimally invasive, catheter-based treatments for heart diseases such as aortic valve stenosis, mitral valve stenosis, mitral valve regurgitation, patent foramen ovale, and atrial septal defects.

Dr. Czarny's research interests include the safety of cardiac stenting at hospitals without cardiac surgery backup and outcomes of catheter-based structural heart procedures. more
