How successful is the cath radiofrequency ablation for wpw treatment?

Highly successful: Overall success depends where the accessory WPW is located in the heart, but with modern ep mapping systems, the procedure has a high success rate. Recurrence can occur due to another accessory pathway showing up later.

Very effective: Catheter-mediated radiofrequency ablation is the preferred therapy for treatment of accessory pathways (ap). The success rate rivals that of surgery, with a comparable or lower mortality and a lower acute morbidity. Numerous series have reported success rates of 90 to 95 percent, depending upon the location of the ap and the precision of localization of the pathway.
