About Michael Flanagan, MD

Dr. M. Casey Flanagan, MD, FACC, is board certified in internal medicine, cardiology and advanced heart failure and transplant. In addition, he has a special interest in managing cardiogenic shock and critical care cardiology. Dr. Flanagan also serves as the Medical Director of Inova Sports Cardiology, a collaborative program between Inova Sports Medicine and Inova Heart and Vascular Institute, focused on the unique cardiovascular needs of competitive and recreational athletes.

As a military cardiologist, he focused on returning service members with cardiac disease to their duties and worked closely with athletes at the service academies.
