CAN ASYMPTOMATIC WOLFF-PARKINSON-WHITE PATTERN BE A RISK FACTOR FOR DEVELOPMENT OF DILATED CARDIOMYOPATHY?

Abstract

Wolff-Parkinson-White (WPW) syndrome is a well known pre-excitationsyndrome and associated with supraventricular tachycardia (SVT). Dilatedcardiomyopathy (DCM) is the most common type of cardiomyopathy and it mayarise in patients with symptomatic WPW. However, WPW with accessorypathway and without incessant tachyarrhythmia, may cause left ventricle septaldyskinesia and left ventricle dysfunction. Recovery of the left ventricle functionafter the ablation or medical treatment shows the association between DCM andventricular pre-excitation. In this case report, we present an asymptomatic WPWpatient who developedDCMand was successfully treated with ablation therapy.Key Words: Accessory pathway, Asymptomatic Wolf-Parkinson-WhiteSyndrome, Dilated cardiomyopathy
