What is a atrioventricular (AV) node ablation?
Atrioventricular (AV) node ablation is a cardiac catheterisation procedure to treat atrial fibrillation, which prevents the upper chambers (atria) sending faulty electrical impulses to the lower chambers (ventricles). Radiofrequency energy (heat) is applied through a catheter to the pathway connecting the chambers of the heart, which destroys a small area of tissue and disrupts the electrical link.
Before the procedure, several tests are undertaken and in all cases patients are fitted with a pacemaker prior to the AV node ablation procedure.
Following the procedure, your symptoms are likely to improve to the extent that you won't need to take medication to control your heart rate. However, you may need to continue to take blood-thinning medication to reduce the risk of suffering a stroke.
