Cryoablation of AF: Improving the Use of the Achieve Catheter
- Conditions
- Atrial Fibrillation
- Interventions
- Other: Maneuvers for documenting the disconnection
- Registration Number
- NCT01843465
- Lead Sponsor
- Clinique Pasteur
- Brief Summary
According to data from high volume Centres, documentation of entry block with the Achieve catheter may be possible in only about to 50% of pulmonary veins. The investigators aim to assess strategies using the Achieve catheter that can improve this performance.

Group Intervention Description Cryoablation of atrial fibrillation Maneuvers for documenting the disconnection -
- Primary Outcome Measures
Name Time Method Real-time Documentation of Pulmonary Vein Disconnection atrial fibrillation cryoablation procedure Possibility of real-time documentation of the pulmonary vein during cryoballoon ablation, through the use of the Achieve catheter. This will be codified as "yes" or "no", and in case of an affirmative answer Final results will be expressed as a % of the total pulmonary veins where disconnection was documented in real-time and the time of maneuver of the Achieve catheter that was necessary i.e. standard position (type 1); withdrawal position (type 2) or need of pacing (type 3). A pulmonary vein where no real-time documentation is possible, will be named as a type 4.
