Overview of Stereotaxis

Stereotaxis Robotic Navigation Technology uses computer-controlled magnets — positioned on either side of the patient table — to steer catheters through the patient's blood vessels and heart chambers. This technology is used with ablation to treat irregular heartbeats. 

Robotic navigation allows your doctor to steer catheters with highly precise control. The tip of the catheter used is soft and magnetic and responds to the magnetic fields in the procedure room. The magnetic fields are very safe and have less than 10% of the strength of fields typically generated during a MRI.

Robotic control means your doctor can make finer, more accurate movements of the catheter when it is positioned inside your heart. This allows for increased accuracy in identifying and treating the abnormal heart tissue responsible for rhythm problems. In addition, the softness of the catheter tip significantly reduces the risk of cardiac perforation – a hole created in the heart. Perforation, though it occurs rarely, can be a cause of significant bleeding in these procedures.

Stereotaxis is appropriate for patients with all types of heart rhythm disturbances. These include arrhythmias of the top chambers such as atrial fibrillation , as well as of the bottom chambers including premature ventricular contractions (PVCs) and ventricular tachycardia. During a stereotaxis procedure, a catheter is inserted in an artery in the patient's leg and guided into the heart. Then, real-time, three dimensional images of the heart are generated using the stereotaxis catheter in conjunction with a computerized 3D mapping system.


Images created during stereotaxis procedures have color coding that indicates electrical activity. The result is an advanced road map of your heart tissue. Using the map and the navigation system, the doctor will steer the catheter using push button and joystick controls to ablate (destroy) small targeted areas of your heart muscle. By destroying the area responsible for the abnormal rhythm, ablation restores a normal heartbeat.

Intermountain Heart Institute was the first in Utah and the Intermountain West to offer stereotaxis technology and our case volumes are among the highest in the nation. Due to our extensive experience, we are active in teaching visiting physicians about this technology. We have also been among the first in the nation to combine this technology with other advanced treatments, such as temporary heart assist devices for patients with poor heart function.

Patient Instructions

Please review the patient instructions from the cardiovascular cath lab, for important information on pre-registration, completing your health history form, and scheduling arrival times:

Where Do I Go?

On the day of your procedure, you need to come to Intermountain Medical Center – Building 4 (Heart & Lung Center). Follow the signs to Patient Registration on the first floor. Once you are registered, we will take you to a room in our Cardiac Procedure and Recovery Unit. When it is time for your procedure, you will be taken to the CV Cath Lab.

If you have questions please call us: 801-507-4701.
