Comparison of 3 RF Delivery Modes of the QDOT Catheter for Paroxymal Atrial Fibrillation (AF) Ablation
Sponsor: Institut Mutualiste Montsouris
Summary
Pulmonary vein isolation is the main treatment of paroxysmal and persistent atrial fibrillation. The aim of our study is to prospectively compare the efficacy and safety of the 3 options of radiofrequency delivery with QDOT Micro™, with systematic use of catheter stabilization tools and tighter lesions

Interventions
Q-MODE : radiofrequency ablation up to 50W
The same device (QDOT Micro™) is used in all 3 arms of this trial. The 3 strategies of radiofrequency delivery within the 3 arms are already used in the standard of care. For patient randomized in this arm, the device is set to Q-MODE option: the intensity of radiofrequency to isolate the pulmonary vein is limited to 50W.
Q-MODE+ : radiofrequency up to 90W
The same device (QDOT Micro™) is used in all 3 arms of this trial. The 3 strategies of radiofrequency delivery within the 3 arms are already used in the standard of care. For patient randomized in this arm, the device is set to Q-MODE+ option: the intensity of radiofrequency to isolate the pulmonary vein is limited to 90W.
Hybride Q-MODE/Q-MODE+: radiofrequency ablation up to 50W in the anterior part, and 90W in the posterior part
The same device (QDOT Micro™) is used in all 3 arms of this trial. The 3 strategies of radiofrequency delivery within the 3 arms are already used in the standard of care. For patient randomized in this arm, the device is set to "Q-MODE/Q-MODE+" option: the intensity of radiofrequency delivered to isolate the pulmonary vein is limited to 50W in the anterior part and to 90W in the posterior part.
