Catheter ablation is a treatment in which a specific area of the heart is frozen (cryoablation) or heated (radiofrequency ablation) in order to prevent the generation or spread of abnormal electrical impulses that cause an abnormal heart rhythm. Catheters are long, thin tubes that are passed to the heart by way of a vein, or occasionally artery, in the groin. These catheters are used to make electrical recordings from the heart and to deliver ablation energy. Like all medical procedures, catheter ablation carries a risk of complications. The overall risk of a complication and the risk of individual complications varies depending on the heart rhythm being treated and on certain patient-related factors. Your consultant will discuss these with you, together with the risks and benefits of other treatment options such as drugs.
