AutoMatic disPERsion Tagging Function Preliminary Evaluation (AMPERE)

November 17, 2023 updated by: Volta Medical

Preliminary Evaluation of the Artificial Intelligence Software VX1+ for the Detection and Automatic Tagging on 3D Mapping of Spatio-temporal Dispersion Areas During Atrial Fibrillation or Atrial Tachycardia Ablation Procedures.

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.

Study Overview

Detailed Description

Ablation of Atrial Fibrillation (AF) and Atrial Tachycardia (AT) is typically performed in predetermined anatomic regions of the left atrium (pulmonary veins isolation) and may be supplemented by a tailored ablation approach in order to identify areas of interest specific to the patient. The VX1+ medical device is intended to assist operators in the manual or automatic real-time annotation of 3D electroanatomical maps of the heart for the presence of multipolar intra-cardiac atrial electrograms exhibiting spatio-temporal dispersion during ablation procedures.

This study will specifically allow to evaluate the peroperative performance of VX1+ automatic tagging function in bi-directional configuration with a compatible 3D mapping system.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Atrial mapping and dispersion auto-tagging with VX1+
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.

What is the study measuring?
