Key result
Slow pathway ablation for AVNRT achieves ~97% long-term rhythm control with rare late AV block.
Why the study?
Slow pathway radiofrequency ablation is effective for AVNRT, but has been reported in some series to cause late atrioventricular block.
Does radiofrequency slow pathway ablation for AVNRT result in a high rate of late atrioventricular block?
Cohort (n=1,256)
No
Does radiofrequency slow pathway ablation for AVNRT result in a high rate of late atrioventricular block?
Radiofrequency slow pathway modification for AVNRT is highly effective and safe, with a very low incidence of late atrioventricular block (0.58 per 1000 patient years) that is comparable to background population rates.
No takes yet. Share an insight, caveat, or question.
Supports durable AVNRT control with minimal late AV block; extends observational cohorts but leaves randomized confirmation open.
Yaakop et al. (2026) conducted a cohort in Atrioventricular nodal re-entrant tachycardia (AVNRT) (n=1,256). Radiofrequency slow pathway ablation was evaluated on Long-term rhythm control. Radiofrequency slow pathway ablation for AVNRT achieved long-term rhythm control in 97% of patients, with a low incidence of late atrioventricular block (0.58 per 1000 patient-years).
