What is radiofrequency catheter ablation?

Radiofrequency catheter ablation is a treatment for atrial fibrillation that wipes out the tissue in your heart that creates erratic electrical impulses. If other treatments such as drug therapy or cardioversion don't successfully treat your atrial fibrillation, your doctor might suggest this procedure. If your atrial fibrillation is caused by "hot spots" of electrical energy that fire at a fast rate, radiofrequency catheter ablation can scar the tissue of these hot spots to prevent them from sending impulses. This procedure is done through a narrow tube put in an artery by your collarbone or leg which sends radiofrequency energy.
