- Cryoablation is a treatment for cardiac arrhythmias, which are abnormalities or disturbances in the rate or rhythm of the heartbeat.
- Cryoablation is similar to radiofrequency ablation but uses extreme cold (cryo), rather than electric current, to damage targeted heart tissue that is causing an arrhythmia.
- During cryoablation, a physician inserts a catheter (thin, flexible tube) into the heart and freezes tiny areas of the heart muscle that cause the abnormal heart rhythm.
- Physicians use cryoablation to treat a type of atrial fibrillation that cannot be treated with medicines.
Physicians use the Arctic Front® Cardiac CryoAblation Catheter for a cryoablation procedure. It is a steerable, flexible plastic tube (catheter) with a balloon at its tip that expands when filled with coolant delivered from the CryoConsole, a computerized control center.
