Biography

    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 and of the American Society of Echocardiography, where he sits as a member of the Committee for Continuing Medical Education. 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‚Äôs 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 immigrantpopulations.   

     

Research

  • It is thought that the left atrial function 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 presystolic contraction of the mitral annulus.
  • 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.
  • 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

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Silbiger did not report having any of the following types of financial relationships with industry during 2014 and/or 2015: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
