Key result
Machine prediction of AVNRT ablation sites aligns with operator selection in ~86% of cases.
Why the study?
Conventional techniques performed by an experienced operator had not previously been compared to novel mapping techniques for AVNRT ablation.
Does novel electroanatomical mapping concord with traditional operator prediction for identifying ablation sites in patients undergoing AVNRT ablation?
Population
14 consecutive patients undergoing AVNRT ablation
Comparison
Operator prediction vs machine prediction from sinus collision mapping
Design
Retrospective cohort study with operator blinded to mapping

Does novel electroanatomical mapping concord with traditional operator prediction for identifying ablation sites in patients undergoing AVNRT ablation?
Novel electroanatomical mapping techniques show high concordance (85.7%) with an experienced operator's predictions for AVNRT ablation sites, suggesting they are useful supplementary tools.
Antharam et al. (2025) conducted a cohort in Atrioventricular Nodal Reentry Tachycardia (AVNRT) (n=14). Traditional/hybrid method (operator prediction) vs. Ensite X mapping (machine prediction) was evaluated on Concordance between operator and machine-predicted location (distance within 4 mm). Operator prediction of the ablation site coincided with machine prediction in 85.7% of AVNRT ablation cases, with an average distance of 1.75 mm between the two points.
