Radiofrequency endocardial catheter ablation of accessory atrioventricular pathway atrial insertion sites.
Why the study?
Is radiofrequency ablation at the accessory pathway atrial insertion site safe and effective in patients with accessory pathway-mediated tachycardia?
Population
114 patients with accessory pathway-mediated tachycardia (symptomatic Wolff-Parkinson-White syndrome)

Implication
Supports atrial insertion ablation for accessory pathways; leaves open randomized confirmation versus ventricular approaches.
Structured PICO
Is radiofrequency ablation at the accessory pathway atrial insertion site safe and effective in patients with accessory pathway-mediated tachycardia?
P
Population
114 patients with accessory pathway-mediated tachycardia (symptomatic Wolff-Parkinson-White syndrome)
I
Intervention
Radiofrequency current ablation at the accessory pathway atrial insertion site using a transvenous approach (transseptal for left-sided pathways)
O
Outcome
Safety and efficacy of accessory pathway ablation (asymptomatic status and absence of accessory pathway conduction)
Radiofrequency ablation at the atrial insertion site is a safe and highly effective approach for treating accessory pathway-mediated tachycardia, avoiding the risks of retrograde ventricular approaches.
