Dr. Sammy Elmariah is an interventional cardiologist who specializes in caring for patients with heart valve disease, coronary artery disease, and adult congenital heart disease. He has particular interest and renowned expertise in transcatheter heart valve procedures including transcatheter aortic valve replacement (TAVR), edge-to-edge mitral valve repair (MitraClip and TEER), mitral valve replacement (TMVR), and the use of investigational devices for repair and replacement of the tricuspid valve.
Dr. Elmariah's research focuses on the prediction and optimization of clinical outcomes of patients with aortic stenosis and after transcatheter aortic valve replacement. Aortic valve stenosis is a disorder predominantly affecting the elderly and characterized by severe narrowing of the aortic valve, the doorway through which blood exits the heart. Aortic stenosis ultimately leads to heart failure and death. Surgical or transcatheter replacement of the valve cures the valve obstruction, but valve replacement is routinely reserved until compensatory mechanisms within the heart have failed. For many patients, this point is too late. Despite valve replacement, damage to the heart muscle may be permanent, resulting in persistent symptoms and increased risk for death. Methods capable of identifying early stages of irreversible heart injury due to aortic valve stenosis are needed in order to help optimize the timing of surgery.
