title: An infant with heart failure due to ventricular dyssynchrony and refractory tachycardia caused by a right anterolateral accessory pathway.
abstract: Wolff-Parkinson-White syndrome is associated with heart failure (HF) mainly via tachycardia. Several case report series have suggested dyssynchrony due to an accessory pathway as a possible cause of HF even in the absence of tachyarrhythmias. The role of cardiac resynchronization in the suppression of anterograde conduction of accessory pathways by catheter ablation or pharmacotherapy in such patients remains unclear, especially in the pediatric population. We describe an infant case with HF due to ventricular dyssynchrony and refractory tachycardia caused by a right anterolateral accessory pathway. Cardiac resynchronization either by catheter ablation or amiodarone appears to be of value in such cases.
