Overview
Bundle of Kent is an accessory conduction pathway between the atria and ventricles in the heart.
Pathophysiology
Bundle of Kent is an abnormal pathway present in a small percentage of the general population that results in a condition known as Wolff-Parkinson-White syndrome (WPW). The anatomical substrate is a band of myocytes that bridges the fibrous junction between the atrium and the ventricle.
Natural History, Complications, Prognosis
Problems arise when this pathway creates an electrical circuit that bypasses the AV node. The AV node has rate-slowing electrical (regulation) properties, whereas the pathway via the bundle of Kent does not. When an aberrant electrical impulse travels through the Kent bundle, tachyarrhythmia ensues.
Treatment
In order to treat persons with Wolff-Parkinson-White syndrome, destruction of the bundle of Kent is accomplished by radiofrequency catheter ablation. This procedure is performed almost exclusively by cardiac electrophysiologists.
