Division of Cardiology

Gregory Dehmer, MD

Director, Division of Cardiology

The Scott & White Division of Cardiology, a part of the Scott & White Heart & Vascular Institute, maintains a strong reputation as a leader in treating cardiovascular disease.

The Division of Clinical Cardiology is often the entry point for access to all of the complex services available at the Scott & White Heart & Vascular Institute. Patients with very common heart problems, such as angina, leaking heart valves, heart failure and heart rhythm disturbances, as well as some very rate forms of heart disease, are evaluated in the clinic. Physicians perform the initial exams of the patients and then obtain help from other more specialized members of the division, if necessary.
