Underestimated Recurrence Rates after Ablation for Wolff-Parkinson-White Syndrome and Impact on Follow-up Practices

The risk of recurrence after accessory pathway (AP) ablation in patients with Wolff-Parkinson-White (WPW) syndrome ranges between 5-12%.1-3 Given practice variation in duration of follow up after successful AP ablation, data on recurrence risk is largely limited to the first year following catheter ablation2. Cases of late recurrence at our institution prompted us to describe our institutional experience including long-term risk of recurrence of WPW pattern on ECG, accessory pathway characteristics before and after recurrence, and the proportion of recurrence that is symptomatic or asymptomatic to better guide follow-up practices.
