In this episode of We’re All Heart, Dr. Barry Bertolet sits down with Dr. Murray Estess, a non-invasive cardiologist and echocardiography expert at North Mississippi Health Services. Together, they explore the power of 3D echocardiography—how it works, what it reveals, and why it’s transforming patient care.

From diagnosing heart valve disease and congenital defects to planning surgeries and detecting rare tumors, Dr. Estess explains how this advanced imaging technology brings the heart into sharper focus—without a single incision. You’ll also hear about his journey from pharmacy to cardiology, what brought him back to Mississippi, and what “True North” means to him and the team.
