Brief Summary

This PMCF study "VOLTAIRE-AF" will allow to observe acute and long-term safety and performance outcomes of the last generation of Volta Medical AI software (Volta AF-Xplorer II) during AF ablation using next-generation mapping and ablation technologies over a 24-month follow-up and in "real life"clinical practice, without any imposed clinical workflow.

Outcome Measures

Primary Outcomes (3)

  • Freedom from clinically significant AF or atrial arrhythmia recurrence, after one or multiple ablation procedures, with or without antiarrhythmic drugs, at 12 and 24 months.

    An Atrial Arrhythmia episode (AF/AFL/AT ≥ 30s) will be determined to be clinically significant if it results in an unexpected treatment change (e.g. new anti-arrhythmic drug or higher dose of AAD, repeat ablation procedure, DC cardioversion), or if it is accompanied by worsening of symptoms related to AF, considering a standard 3-month blanking period.

    24 months

  • Volta AF-Xplorer II-related Serious Incident rate

    24 months

  • Ablation procedure-related Serious Adverse Event rate

    24 months

Secondary Outcomes (9)

  • Progression of Quality-Of-Life score ("EQ-5D-3L") during the study (at inclusion, at quarterly visits, at 12 months and at 24 months).

    24 months

  • Progression of the AF related symptom score ("EHRA") during the study (at inclusion, at quarterly visits, at 12 months and at 24 months).

    24 months

  • Progression of the Heart Failure related symptom score ("NYHA") during the study (at inclusion, at quarterly visits, at 12 months and at 24 months).

    24 months

  • Hospitalization rate during the post-ablation follow-up period.

    24 months

  • Serious Adverse Event rate during the post-ablation follow-up period.

    24 months

  • +4 more secondary outcomes

Interventions

All patients enrolled are treated for their atrial fibrillation/tachycardia via a catheter ablation procedure using the last generation of Volta Medical AI software (Volta AF-Xplorer II, used in accordance with its approved indication as per of its IFU) during the mapping phase to identify areas of interest specific to the patient. The ablation approach is free and chosen by the operator according to his standard practice. The two main phases of the ablation procedure are: * 3D mapping of the atria and location of areas of interest; * Catheter ablation at the operator's discretion.

Also known as: Atrial fibrillation mapping, Ablation procedure
