Key result
Manifest WPW is linked to an ~8-fold higher rate of multiple accessory pathways versus concealed WPW.
Why the study?
Does radiofrequency catheter ablation have similar success and recurrence rates in WPW syndrome patients with multiple accessory pathways compared to those with single accessory pathways?
Observational (n=74)
No
Does radiofrequency catheter ablation have similar success and recurrence rates in WPW syndrome patients with multiple accessory pathways compared to those with single accessory pathways?
Radiofrequency catheter ablation is an effective treatment for WPW syndrome patients with multiple accessory pathways, yielding success and recurrence rates comparable to those with single pathways.
May prompt enhanced mapping in manifest WPW; leaves open effects on ablation outcomes in larger cohorts.

Ikeguchi et al. (1998) conducted an observational in Wolff-Parkinson-White (WPW) syndrome (n=74). Radiofrequency catheter ablation vs. Concealed WPW syndrome (for the comparison of multiple pathways incidence) was evaluated on Incidence of multiple accessory pathways (p=<0.01). Multiple accessory pathways were identified significantly more frequently in patients with manifest WPW syndrome (24%) compared to those with concealed WPW syndrome (3%).
