    Catheter Ablation Procedure for Treating Atrial Fibrillation (A-Fib)

    Catheter ablation is a minimally invasive, low-risk surgical option to treat patients with symptomatic, irregular heartbeat by destroying (ablating) the heart cells that are sending an irregular signal. Although it is not the primary choice of treatment for arrhythmia, it can be effective if medications or other interventions to control an irregular heart rhythm don’t work.
