Overview

Atrioventricular nodal 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 controls the heart rate and rhythm) and the lower chambers (ventricles). AVNA is mostly as a fallback treatment in patients with atrial fibrillation that is refractory to medications, or have developed side effects to the medications.
