Kristin Lorraine Martin, MD

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, interventional cardiology, and structural heart disease fellowships at Johns Hopkins. Currently, he is a faculty member in interventional cardiology and performs heart catheterizations 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. He is also a member of the Structural Heart Disease team and performs minimally invasive, catheter-based treatments for structural heart disease at the Johns Hopkins Hospital including transcatheter aortic valve replacement (TAVR) for aortic valve stenosis, valve repair/replacement procedures for mitral valve regurgitation and stenosis, patent foramen ovale closure, atrial septal defect closure, alcohol septal ablation for hypertrophic cardiomyopathy, and left atrial appendage occlusion with the Watchman(TM) device. He sees patients in his structural heart disease clinics at both the Johns Hopkins Hospital and the Johns Hopkins Bayview Medical Center.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.

Dr. Raman is a Nephrologist at Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center.
