Texas Cardiac Arrhythmia

What Texas Cardiac Arrhythmia does

Texas Cardiac Arrhythmia (TCA) is a private, physician-led cardiac electrophysiology practice founded in 2009 and headquartered in Austin, Texas. The firm diagnoses and treats heart rhythm disorders — atrial fibrillation, atrial flutter, ventricular tachycardia, ventricular fibrillation, sick sinus syndrome, and related conduction abnormalities — through a comprehensive service line spanning electrophysiology studies, catheter ablation (radiofrequency, cryoablation, and pulsed field), pacemaker and implantable cardioverter defibrillator (ICD) implantation, cardiac resynchronization therapy, WATCHMAN left atrial appendage occlusion, and lead extraction. Patient-facing services are delivered via telehealth and across 10+ clinic locations spanning Austin, Dallas, Houston, Amarillo, El Paso, Corpus Christi, Bryan, San Marcos, and Round Rock in Texas plus Lake Charles, Louisiana, with international patient services extending the reach globally.

The practice's technology backbone rests on the Texas Cardiac Arrhythmia Institute at St. David's Medical Center (within the HCA Healthcare system), which combines specialized EP labs with advanced mapping platforms such as the CARTO 3 system and early-adopter access to Johnson & Johnson MedTech's QDOT MICRO Catheter for zero-fluoro ablation. TCA functions as a clinical research site for investigational devices from Abbott, Boston Scientific, Medtronic, Biosense Webster, and others, and was first in the U.S. to implant an FDA-approved novel miniaturized catheter-delivered defibrillation lead in January 2026. Education and thought leadership are anchored by the EPLive biennial international symposium, which drew a record 1,600 global participants in 2026.

TCA generates revenue on a fee-for-service professional services basis, billing through commercial insurance (Aetna, Blue Cross Blue Shield, Cigna, Humana, United Healthcare), Medicare/Medicare Advantage, Medicaid, and offering indigent and discount programs. The customer base is highly fragmented individual patients with heart rhythm disorders, supplemented by referring primary care physicians and cardiologists and an active clinical trials program. Leadership is concentrated around Executive Medical Director Dr. Andrea Natale (former Cleveland Clinic Center for Atrial Fibrillation director, FDA Task Force member), with a multi-state roster of board-certified electrophysiologists delivering care within HCA's facility infrastructure.
