structural heart

Any time an abnormality or defect weakens the heart’s structure – its walls, valves and muscles—it’s referred to as structural heart disease. In a healthy heart, the four valves work together to move blood from the upper to the lower chambers, pushing it out to the lungs and other organs. One or more defective valves can affect the heart’s normal function and may lead to serious health complications.

Structural heart defects can be treated through traditional open-heart surgery, or through several minimally invasive procedures.

"Having trained with some of the best in the world at Brown University in three specialties, endovascular peripheral arterial disease, structural heart and complex/high-risk coronary disease, I feel very fortunate to have the skills and expertise to help patients who are seriously ill. Working at CMC’s New England Heart & Vascular Institute, I have the privilege to practice all three of these specialties at the highest level with the latest technologies. It is humbling to know I can make a difference in the lives of patients."
