Catheter ablation is a minimally-invasive procedure used to remove or terminate a faulty electrical pathway from sections of the hearts of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter, supraventricular tachycardias and Wolff-Parkinson-White syndrome. If not controlled, arrhythmias increase the risk of ventricular fibrillation and sudden cardiac arrest. The procedure can be classified by energy source: radiofrequency ablation and cryoablation.
