Reversal of Wolff-Parkinson-White Syndrome induced dilated cardiomyopathy via resynchronization and subsequent accessory pathway ablation

Recurrent or incessant tachycardia is frequently found in symptomatic Wolff-Parkinson-White （WPW） syndrome, leading to ventricular dysfunction, dilated cardiomyopathy （DCM） and heart failure in infants and children.[1] Recently, Winter, et al.[2] report that WPW syndrome could provoke many kinds of cardiac dysfunction, leading to remodeling and progressive ventricular dilatation through pre-excita- tion-related dyssynchrony, even without arrhythmia.
