NCT05362656

Brief Summary

Interventional, prospective, non-randomized, single-center, non-controlled clinical investigation as part of the premarket clinical evaluation of VX1+ medical device, aiming to verify that VX1+ in bidirectional configuration with auto-tagging function is both ergonomic and reliable for dispersed electrograms detection and automatic tagging on 3D-map in real-time.

Outcome Measures

Primary Outcomes (1)

  • Perioperative reliability of VX1+ in the real-time detection of electrograms in AF or AT exhibiting a spatio-temporal dispersion, and auto-tagging of these dispersion areas on 3D electroanatomical maps.

    Comparison between the automatically annotated areas with VX1+ and those annotated manually following the operator's visual analysis (true positive, false positive, false negative).

    During procedure

Secondary Outcomes (3)

  • Accuracy of VX1+ in estimating cardiac cycle lengths

    During procedure

  • Operators' satisfaction regarding the ergonomics of VX1+

    Through study completion, assessed up to 4 months

  • Preliminary safety data on VX1+ perioperatively in terms of device deficiencies, adverse events and mapping time

    From the date of hospitalization for the ablation procedure until the date of discharge, up to 1 week

Study Arms (1)

Atrial mapping and dispersion auto-tagging with VX1+

EXPERIMENTAL
Device: VX1+ dispersion mapping

Interventions

Careful biatrial high density dispersion mapping is performed as the first step of the procedure. Operators map each region of both atria carefully by moving the mapping catheter slowly. If VX1+ application detects dispersion regions, the corresponding dipoles location will be automatically tagged on the 3D-map. Accuracy and relevance of dispersion regions should be confirmed by the operator by checking EGMs visually.
