text: Atrioventricular<unk>  or AV junction ablation is a procedure by which the electrical pathways that connect the atria to the ventricles are modified or interrupted in order to restore a normal cardiac rhythm. This procedure creates a disconnect between the upper chambers (which control the heart rate and rhythm) and the lower chambers (ventricles). Due to the invasive nature of this procedure and the requirement of pacemaker implantation, AVNA is mostly done as a fallback treatment in patients with atrial fibrillation that is refractory to medications, or have developed side effects to the medications. It is important to note that this procedure is not a cure for atrial fibrillation, its function is to regulate the ventricular rate. Therefore, patients will still require life-long anticoagulation.
