title: [The radiofrequency and the elimination of accessory atrioventricular pathways. The factors related to successful transcatheter ablation].
abstract: Some factors related with successful radiofrequency catheter ablation were retrospectively analyzed from the initial patients with WPW syndrome that underwent this therapy. They were 21 patients, and success rate with radiofrequency therapy was 73%. Conventional conduction intervals were obtained from catheter ablation electrograms. Only ventricular activation around Delta-wave onset, and earliest retrograde atrial activation were statistically significant for successful ablation (P < 0.05 both). Inadvertent interruption of AV-His bundle was produced ablating a septal accessory pathway, and no mortality procedure-related was observed. We conclude that radiofrequency catheter ablation of accessory pathways represents nowadays, an effective solution in patients with symptomatic arrhythmias, besides its high success rate and low risks, but different mapping criteria should be considered to attain an efficient elimination of atrioventricular accessory-pathways.
