Catheter ablation is a minimally invasive surgical procedure used to treat heart arrhythmia, a condition where there is a problem with the rhythm or the rate of your heartbeat. Also known as cardiac ablation, this procedure involves guiding a small tube, or catheter, through the veins and into the heart where electrodes at the end of the catheter are used to eliminate the heart cells causing arrhythmia. Catheter ablation is most often recommended for patients whose arrhythmia cannot be managed by medication or other forms of treatment.
The catheter ablation procedure typically lasts 3 to 4 hours. After the patient is sedated (either IV sedation or general anesthesia), the doctor makes a small incision in the skin of the groin (and, rarely, the arm or neck) after which a guide wire and catheter are inserted and then directed through the blood vessels to the heart. The electrodes are used to stimulate the heart and find the problem areas that are causing the arrhythmia. These areas are usually quite small, roughly one-fifth of an inch. Using radiofrequency energy to heat the tissue or cryoablation to freeze the tissue, the electrophysiologist then destroys or "ablates" the problem cells. After the ablation, the electrical signals that caused the arrhythmia will no longer be sent to the rest of the heart.
Catheter ablation is not painful, though patients may feel some discomfort while the catheter is in the chest. Following the ablation procedure patients must rest for at least 4 hours while being monitored.
