VOLta Medical AI-software in REal-World During AF Ablation (VOLTAIRE-AF)

May 27, 2026 updated by: Volta Medical

Real-World Experience of Volta Medical AI-software During AF Ablation Using Next-generation Mapping and Ablation Technologies

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.

Detailed Description

All patients enrolled are treated for atrial fibrillation/tachycardia via a catheter ablation procedure using the last generation of Volta Medical AI software (Volta AF-Xplorer II) 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 standard practice. Intraoperative and postoperative follow-up will be performed as in routine clinical practice during AF ablation procedures: hospitalization for ablation procedure and standard postoperative quarterly visits (at 3 months, at 6 months and/or 9 months as per the study investigator's Standard Of Care) then annual visits up to 24 months post-ablation. Adverse Events, recurrences of atrial arrhythmia, Heart Failure related symptom score ("NYHA") and AF related symptoms (EHRA score) are collected from the patient's enrollment until the patient's study termination. A quality-of-life questionnaire related to general health (EQ-5D-3L) is collected during the preoperative visit and at least during annual follow-up visits. The patient's study-termination corresponds to the last annual visit at 24 months post-ablation index.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Time Frame: 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.

Volta AF-Xplorer II-related Serious Incident rate
Time Frame: 24 months
24 months
Ablation procedure-related Serious Adverse Event rate
Time Frame: 24 months
