I have fast heartbeat symptoms.

Cardiac Arrhythmia A fast or irregular heartbeat can sometimes feel like a flutter. Afib is the result of these abnormal rhythms. LEARN MORE

I’ve been diagnosed with Afib.

Atrial Fibrillation There are many kinds of Afib treatments that can control your symptoms and reduce your risk of stroke. LEARN MORE

My medication is not working.

Medication If your rate or rhythm control medication is ineffective, and you have paroxysmal Afib, you may be a candidate for non-surgical catheter ablation. LEARN MORE

I’m ready for catheter ablation.

Catheter Ablation Patient stories explore how this minimally invasive treatment for Afib has transformed the lives of people just like you. LEARN MORE

The NAVISTAR® THERMOCOOL®, EZ STEER® THERMOCOOL® NAV, THERMOCOOL® SF NAV, and THERMOCOOL SMARTTOUCH® Catheters are FDA approved for the treatment of drug refractory recurrent symptomatic paroxysmal atrial fibrillation, when used with compatible three-dimensional electroanatomic mapping systems. Catheter ablation for AF may not be an option for you if you have any of the following conditions: certain recent heart surgery; prosthetic valves; active systemic infection; certain cancers; intracardiac thrombus, or an interatrial baffle or patch. Consult your physician to find out if catheter ablation is right for you.

Known complications of catheter ablation include the following: bleeding, swelling or bruising at the catheter insertion site, and infection. More serious complications are rare, which can include damage to the heart or blood vessels; blood clots (which may lead to stroke); heart attack, or death.

In the US, THERMOCOOL® Navigation Catheters are approved for recurrent drug/device refractory sustained monomorphic ventricular tachycardia (VT) due to prior myocardial infarction (MI) in adults.
