The Complex Arrhythmia Center at Memorial Hermann Heart & Vascular Institute-Texas Medical Center provides the advanced management and treatment of heart rhythm abnormalities, or arrhythmias including atrial fibrillation which is the most common type of arrhythmia.
The Center provides access to a highly skilled and experienced team specializing in:
- Cardiac VT ablations (a procedure that eliminates the tissue in the heart causing the abnormal heartbeat)
- Lead extractions
- Cardiac resynchronization therapy (CRT)
- Implantation of other rhythmic management devices such as a pacemaker, implantable cardioverter-defibrillator (ICD) or biventricular ICD
Number of Cases
Each year, the affiliated physicians at the Complex Arrhythmia Center perform over 250 atrial fibrillation ablations, 1,400 complex procedures, 700 device implantations, 700 ablations and 50 ventricular tachycardia ablations.
Continuum of Care
The cohesive and collaborative nature of our affiliated specialists and nurses allows the Center to provide patients a seamless continuum of care from initial evaluation through discharge, which is unique to arrhythmia treatment in the Gulf Coast region.
