The NaviStar ThermoCool Catheter is available for the treatment of adults with specific rapid heartbeats who have already experienced failure with other treatments, such as device or other antiarrhythmic drug therapy. These specific rapid heartbeats are scientifically known as ventricular tachycardia (VT) that arise following a heart attack. The catheter is the first FDA-approved catheter to treat both mappable and unmappable VTs. The expanded indication provides cardiac electrophysiologists with a new treatment option for the estimated three million people in the U.S.
