Key result
RFA achieves 99% acute success for typical AVNRT with minimal permanent AV block.
Why the study?
The study aimed to evaluate the acute outcomes of radiofrequency catheter ablation in patients diagnosed with typical atrioventricular nodal reentrant tachycardia.
Does radiofrequency catheter ablation of the slow pathway safely achieve acute non-inducibility in patients with typical AVNRT?
Population
100 patients with typical AVNRT and sustained narrow QRS complex tachycardia
Comparison

Design
Single-center retrospective study

High acute success (99%) with low AV block risk (1%) seen; supports RFA efficacy in this cohort but leaves open need for prospective confirmation.

Does radiofrequency catheter ablation of the slow pathway safely achieve acute non-inducibility in patients with typical AVNRT?
Radiofrequency catheter ablation of the slow pathway is highly effective and safe for typical AVNRT, achieving a 99% acute success rate with a 1% risk of permanent AV block.
Hasan et al. (2024) conducted an observational in Typical Atrioventricular Nodal Reentrant Tachycardia (AVNRT) (n=100). Radiofrequency catheter ablation was evaluated on Non-inducibility of AVNRT. Radiofrequency catheter ablation achieved a 99% acute success rate for non-inducibility of typical atrioventricular nodal reentrant tachycardia with a 1% incidence of permanent AV block.
