The Texas Cardiac Arrhythmia Institute at St. David’s Medical Center (TCAI) is an international treatment, training and research center specializing in heart rhythm disorders—the first of its kind in the U.S. Led by Dr. Andrea Natale, the executive medical director and an international leader in the treatment of heart rhythm disorders, TCAI treats more patients than most practices in the U.S., with a consistently superior success rate.

Cardiologists from around the world receive training at the Institute on the latest electrophysiology procedures and protocols. The Institute’s Cardiac Training Lab allows physicians to observe procedures both on-site and remotely, in real time, interacting with surgeons and researchers to learn how to address even the most challenging arrhythmias.
