Dr. Gautam Kumar is an interventional cardiologist and echocardiographer. Originally from Singapore, he came to the US after completing membership in the Royal College of Physicians in the United Kingdom and did Internal Medicine residency and Cardiovascular Diseases fellowship at the Mayo Clinic in Rochester, MN. Following this, he completed Interventional Cardiology fellowship at Emory University. He has wide-ranging interests from clinical hemodynamics (both invasive and non-invasive), coronary and peripheral intervention, valvular and structural heart disease interventions, biomedical innovation and research and medical ethics.
