Overview
I am an adult cardiac surgeon specializing in heart transplantation and mechanical circulatory support. I perform general cardiac surgery operations, including coronary artery bypass grafting, valve repair, and replacement for various valvular pathologies. A significant portion of my practice is dedicated to the surgical management of patients with advanced heart failure. This includes heart transplantation, left ventricular assist devices (LVAD), and various forms of temporary mechanical circulatory support, such as extracorporeal membrane oxygenation (ECMO). I am proud to be a part of one of the largest volume and highest quality advanced heart failure programs in the world. Duke Health is consistently a national leader in heart transplant volume. We maintain high-quality outcomes and practice at the leading edge of the field. It is a remarkable experience to deliver these innovative therapies to our critically ill heart failure patients. These therapies are not only lifesaving but help restore our patients to the high quality of life they hope to lead.
