Outcome Measures

Primary Outcomes (1)

  • proportion of subjects experiencing 1-year single-procedure clinical success

    The Primary Efficacy Endpoint is the proportion of subjects experiencing 1-year single-procedure clinical success, defined as (2017 HRS consensus statement): 1. Successful index AF ablation 2. Absence of atrial arrhythmia recurrence on any type of recording (≥ 30 sec by TTM (event monitor), Holters, 12-lead ECGs, rhythm strip or other diagnostic ECG documentation), 3. Absence of use of class I or III AAD (except for non-atrial arrhythmia) 4. Absence of redo ablation (except for typical flutter), in the 12 months following the index ablation procedure (including a blanking period of 60 days following the index ablation procedure).

    1 year

Secondary Outcomes (24)

  • proportion of subjects with 1-year multiple-procedures success

    1 year

  • health-related quality of life:

    6 months, 1 year

  • AF-specific quality of life

    6 months, 1 year

  • Death

    7 days, 1 year

  • Stroke

    7 days, 1 year

  • +19 more secondary outcomes

Study Arms (2)

PEF Arm

EXPERIMENTAL

PEF is a non-thermal ablation modality using extremely short high voltage pulses to induce cell death, with tissue selectivity, cardiomyocytes being much more sensitive to this energy than Phrenic nerve or Esophageal cells. Energy (2000 V) will be delivered 8 times per vein with 2 different catheter configurations and rotations

Device: PVI using PEF

Pulmonary vein isolation using Contact Force RF

ACTIVE COMPARATOR

The PVI strategy using RF is very standard. The CARTO© platform will be used, with a contact force catheter (SmartTouch), aiming at an ablation index value of 300 to 400 on the posterior wall, and at least 500 on the anterior wall. Power will be limited to 35/45 W, with a distance between consecutive deliveries of 6 mm or less (CLOSE protocol).

Device: PVI using CFRF
