Radiofrequency ablation for right-free-wall manifest accessory pathway
in a child with asymptomatic Wolff-Parkinson-White syndrome-induced left
ventricular dysfunction
Abstract
Abstract: A 5-year-old male child with asymptomatic
Wolff-Parkinson-White syndrome, cardiac dysfunction and dilated
cardiomyopathy was reported. Electrophysiological study revealed a
manifest accessory pathway on the right free wall. Heart failure and
ventricular remodeling recovered after a successful radiofrequency
ablation in the 10-11 o’clock of the tricuspid annulus. Conclusion: The
dyssynchronous movement of the ventricular septum and left ventricular
caused by right accessary pathway may be the main electrophysiological
mechanism and the prognosis is good after blocking the conduction of
accessary pathway.
