State-of-the-Art Imaging System Offers Enhanced Visualization for Treating
Arrhythmia Patients

AUSTIN, Texas, Nov. 2 /PRNewswire/ -- On Monday, November 2, 2009, Andrea
Natale, M.D., F.A.C.C., F.H.R.S., an electrophysiologist and executive medical
director of the Texas Cardiac Arrhythmia Institute at St. David's Medical
Center, will be the first physician in the United States to perform an
ablation procedure to treat a patient with a cardiac arrhythmia, commonly
known as an irregular heart rhythm, using the newly FDA-cleared CARTO® 3
Navigation System.

"Imaging with the new CARTO® 3 System puts us at the forefront of being able
to visualize and treat nearly every type of arrhythmia," Dr. Natale said. "It
also reinforces our commitment to helping the growing pool of arrhythmia
patients get fast, effective treatment."

The CARTO® 3 Navigation System is a three-dimensional imaging system that
allows doctors to quickly and accurately visualize cardiac anatomy. It is
especially useful in the treatment of atrial fibrillation, or AFIB. AFIB is
the most common type of irregular heart rhythm in the United States, affecting
an estimated 5.6 million people* and is increasing due to the rise in the
aging population.

Texas Cardiac Arrhythmia Institute at St. David's Medical Center offers a full
range of electrophysiology procedures, including catheter ablation--for which
physicians utilize the only FDA-approved catheter for treating AFIB, the
NAVISTAR® THERMOCOOL® Irrigated Ablation Catheter. THERMOCOOL® Navigation
Catheters are approved (for drug refractory recurrent symptomatic paroxysmal
atrial fibrillation) when used with CARTO® 3 Systems.** The CARTO® 3 System
gives doctors the ability to pinpoint the location of these catheters during
ablation procedures with unprecedented speed, precision and clarity.
