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.
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.
