The purpose of this study is to evaluate real-time gap detection using EPD D700 dielectric sensing compared with customary electrical isolation tests and Adenosine infusion at the end of the procedure. Furthermore, safety, usability and clinical applicability of the system for guided AF ablation will be confirmed.

Primary Outcome Measures:
  • Gap detection [ Time Frame: 30 days ]
    Evaluation of ablation gap detection using EPD D700 system.

Estimated Enrollment: 24
Study Start Date: September 2016
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: D700 System
Patients referred to catheter-based Atrial-Fibrillation (AF) ablation procedure therapy comprising of Pulmonary Veins Isolation (PVI).
Device: D700 System
Atrial Fibrillation Ablation Procedure

Detailed Description:

Prospective, single-center, non-randomized, non-blinded, open label, and single arm study.

All procedures will be performed under CARTO-3 guidance for the treatment of atrial fibrillation (AF). The EPD D700 system will be used in-tandem, to record pre-, during and immediate post-ablation tissue characteristics and compute likelihood of lesion transmurality and permanency. Additionally, D700 system safety, feasibility, usability and clinical applicability will be documented.

The entire procedure will be conducted as customary, using standard and approved off-the-shelf equipment (body surface electrodes, diagnostic and irrigated ablation catheters, RF generator and recording system), in a completely clinically independent manner from the EPD D700 system. The physician will neither use nor rely on any of the D700 system output for clinical decision making and will be blinded to the D700 lesion assessment forecasts. After 30 days following the initial procedure, a repeated procedure will be performed for gap detection and its results will be correlated with the D700 predictions.
