Dr. Silbiger completed his residency training in internal medicine at Nassau County Medical Center and his fellowship training in cardiovascular diseases at Beth Israel Medical Center. He is board certified in internal medicine, cardiology and adult echocardiography. Dr. Silbiger is a fellow of the American College of Cardiology as well as of the American Society of Echocardiography, where he sits as a member of the Committee for Continuing Medical Education. Dr. Silbiger joined the faculty of the Icahn School of Medicine at Mount Sinai in 1992 and is presently associate professor of medicine. He currently serves as the director of the Echocardiography Laboratory at Elmhurst Hospital Center, a major teaching campus for the Mount Sinai Clinical Cardiology Fellowship Program. His research interests include: the anatomic basis of mitral annular contraction, the structural mechanics of functional mitral regurgitation and coronary artery disease in high-risk immigrant populations.
- The role played by the left atrium in mitral annulus contraction has not been well characterized and could have implications for mitral annuloplasty ring design. 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 the severity of functional MR is commonly observed in clinical practice, however, its mechanical basis is incompletely understood. Using two and three-dimensional echocardiography and strain imaging, we are studying the role that alterations in annulo-papillary and ventriculo-valvular coupling play in determining MR burden.
South Asians have a significantly higher prevalence of CAD than Caucasians and also suffer from more premature and clinically aggressive disease. We have undertaken a number of studies to characterize the CAD risk factor burdens and angiographic findings of South Asian and Indo-Guyanese immigrants living in New York City. These studies suggest that aggressive screening and risk factor modification are indicated in these populations.

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.
