Cardiac resynchronization therapy for left ventricular dysfunction induced by chronic right ventricular pacing in a child

Abstract

Cardiac resynchronization therapy (CRT) has been proven its value in adult patients with congestive heart failure of low ejection fraction and wide QRS duration. Contrast to adult patients, CRT has been rarely applied for young patients. We report on a 9-yr-old boy with progressive left ventricular (LV) dilatation and dysfunction following chronic VVI pacemaker therapy for congenital complete atrioventricular block associated with maternal anti-SSA/ Ro and SSB/La antibody. His LV dysfunction was improved after epicardially established CRT. © 2010 The Korean Academy of Medical Sciences.
