Dr. Perk is the director of the echocardiography laboratory at the New York Presbyterian / Brooklyn Methodist Hospital. Her main research interests are related to application of emerging echocardiographic techniques into clinical practice. This started with looking at the added benefit of multi-plane transesophageal echocardiography for evaluation of intra-cardiac masses and continued with utilization of portable echocardiographic units, as well as application of new imaging techniques (e.g. strain imaging). In recent years, the emerging role of 3-dimensional echocardiography, in particular as it relates to structural heart disease programs, was at the center of her research efforts.
