Why the study?
To evaluate whether characterization of confluent areas of electrogram fractionation and slow conduction using Omnipolar technology and WaveSpeed mapping provides safer AVNRT ablation targets.
Does ablation guided by Omnipolar technology and WaveSpeed mapping reduce radiofrequency applications and improve safety in patients with AVNRT compared to conventional bipolar 3D mapping?
Comparison
OT-WS mapping/ablation vs bipolar 3D mapping conventional ablation
Design
Non-randomized prospective-multicentric study with a historical comparator group
Follow-up
Median 6 months (OT-WS) vs 5 months (Conventional)

Hypothesis-generating for fewer RF applications in AVNRT; leaves open validation versus conventional mapping in randomized trials.
Does ablation guided by Omnipolar technology and WaveSpeed mapping reduce radiofrequency applications and improve safety in patients with AVNRT compared to conventional bipolar 3D mapping?
High-density mapping targeting confluent areas of slow conduction and fractionation for AVNRT ablation significantly reduces radiofrequency applications and time while maintaining a safer distance from the His bundle compared to conventional ablation.
