Clinical and Healthcare Economic OutcoMes From ReAl-worlD Use in Europe of an AI Software During AF Ablation

The goal of this Observational Prospective Multi-center Study is to observe the acute and long-term safety and performance outcomes after spatiotemporal dispersion-based AF/AT ablation utilizing the Volta Medical AI software in "real-life" clinical practice, without any imposed clinical workflow. Moreover, this study will allow to collect medico-economic data related to the tailored ablation strategy guided by the Volta Medical AI software.

About this study

All patients enrolled are treated for atrial fibrillation/tachycardia via a catheter ablation procedure using Volta Medical AI software 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 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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patient aged 18 years or older.
  • Patient candidate for catheter ablation to treat paroxysmal or persistent atrial fibrillation, atrial tachycardia, de novo or after one or several previous ablation procedures, and for which the investigator considers using VX1 or Volta AF-Xplorer or Volta AF-Xplorer II.
  • Patient able and willing to provide written informed consent to participate in the study.
  • Only for France: Patient affiliated to the French social security system.

Exclusion criteria

  • Contraindication to AF/AT catheter ablation.
  • Patient who is or could potentially be pregnant.
  • Person deprived of liberty or under guardianship.
  • Person unable to undergo a medical monitoring for geographical, social or psychological reasons.
  • Patient's refusal to participate in the study.
  • Enrollment in an investigational study evaluating another device, biologic, or drug.

Treatment and study plan

Cardiac mapping

Device

All patients enrolled are treated for their atrial fibrillation/tachycardia via a catheter ablation procedure using VX1/Volta AF-Xplorer/Volta AF-Xplorer II software (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.

Other names: Atrial fibrillation mapping, Ablation procedure
