Jeffrey Silbiger, MD
- ASSOCIATE PROFESSOR | Medicine, Cardiology
Dr. Silbiger joined the faculty of the Icahn School of Medicine at Mount Sinai after completing his fellowship training in cardiology at Beth Israel Medical Center in New York City. He is board certified in internal medicine, cardiovascular diseases and adult echocardiography. Dr. Silbiger is a fellow of the American College of Cardiology as well as of the the American Society of Echocardiography, where he sits as a member of the Continuing Medical Education Committee. Dr. Silbiger is presently associate professor of medicine and serves as director of the Echocardiography Laboratory at Elmhurst Hospital Center, a major teaching campus for Mount Sinai’s Clinical Track Cardiology Fellowship Training Program. His research interests include the functional anatomy of the mitral annulus, the structural mechanics of functional mitral regurgitation and coronary artery disease in high risk immigrant populations.

- It is thought that left atrium plays a major role in facilitating mitral annular contraction, however, precise structural and mechanical details remain poorly understood. We are performing gross and microscopic anatomic studies in the bovine heart to identify the anatomic substrate of annular contraction. An improved understanding of annular mechanics could have significant implications for future mitral annuloplasty ring designs.
- Heterogeneity in the severity of functional mitral regurgitation is commonly observed in clinical practice, however, the mechanical basis of this phenomenon is incompletely understood. Using two and three-dimensional echocardiography and echocardiographic strain imaging, we are studying the role that alterations in regional left ventricular wall stress, papillary muscle function and ventriculo-valvular interaction play in determining mitral regurgitant burden. An improved understanding of the structural mechanics of functional mitral regurgitation could have important implications for the design of future device therapies.
- South Asian immigrants have a significantly higher prevalence of coronary artery disease than Caucasians and also suffer from more premature and clinically aggressive disease. We have undertaken studies to characterize the risk factor burden and angiographic findings of South Asian and Indo-Guyanese immigrants living in New York City. These suggest that aggressive screening and risk factor modification may be indicated in these populations.
