Key result
Radiofrequency catheter ablation and arrhythmia surgery for atrioventricular nodal reentrant tachycardia demonstrated comparable acute success rates (92% vs 96%) and late recurrence (17% vs 12%).
Why the study?
Does radiofrequency catheter modification compared to surgical modification improve late success and reduce procedure-related arrhythmias in patients with atrioventricular nodal reentrant tachycardia?

RF ablation and surgery yield comparable AVNRT outcomes; leaves open whether RCTs would confirm equivalence or alter side-effect profiles.

Does radiofrequency catheter modification compared to surgical modification improve late success and reduce procedure-related arrhythmias in patients with atrioventricular nodal reentrant tachycardia?
Absolute Event Rate: 92% vs 96%
Radiofrequency catheter ablation and arrhythmia surgery for AVNRT have comparable initial and late success rates, though RF ablation is associated with specific late arrhythmic side-effects like AV block and inappropriate sinus tachycardia.
G. P. Kimman (1999) conducted a cohort in Atrioventricular nodal reentrant tachycardia (n=146). Radiofrequency catheter ablation vs. Arrhythmia surgery was evaluated on Acute success rate. Radiofrequency catheter ablation and arrhythmia surgery for atrioventricular nodal reentrant tachycardia demonstrated comparable acute success rates (92% vs 96%) and late recurrence (17% vs 12%).
