Objective
Optimal management in asymptomatic children and adolescents with the Wolff–Parkinson–White (WPW) electrocardiographic pattern is still debatable. The aim of this retrospective study was to evaluate the electrophysiological properties of asymptomatic children and adolescents with WPW.
Methods
The medical records and procedural data of asymptomatic children and adolescents with the WPW electrocardiographic pattern who underwent invasive electrophysiologic study (EPS) and catheter ablation between April 2012 and April 2018 were evaluated.
Results
We retrospectively investigated 149 consecutive asymptomatic children and adolescents with WPW who underwent EPS. A shortest pre-excited R–R interval (SPERRI) ≤250 ms during atrial fibrillation or accessory pathway effective refractory period (APERP) ≤ 270 ms were found in 39 (26.2 %) of the patients. 39 patients with high risky antegrade conduction and 45 patients with inducible orthodromic atrioventricular re-entrant tachycardia underwent catheter ablation. Additionally 14 patients underwent catheter ablation because of family preference.
Conclusion
High risk antegrade conduction properties are exhibited by more than one quarter of asymptomatic children and adolescents with WPW. Ablation should be considered as a firstline therapy in asymptomatic children and adolescents with high risk WPW.
