- Composite Safety Endpoint;Proportion of Intent to Treat Subjects with one or more of the specified device or procedure related SAEs [ Time Frame: 7 days and 12 Months ]Proportion of Intent to Treat subjects with one or more of the specified device or procedure related SAEs
- Treatment success [ Time Frame: 12 Months ]Acute procedural success and Chronic success
- Primary Effectiveness Endpoint [ Time Frame: 12-Months ]
Treatment Success: The primary effectiveness endpoint is Treatment Success in MITT Subjects, defined as:
- Acute Procedural Success AND
-
Chronic Success, defined as freedom from:
- At the Index / Rescheduled Index Procedure: Use of a non-randomized treatment modality for PVI
- After the Blanking Period:
i. Occurrence of any Detectable AF, AFL or AT (excluding CTI-dependent flutter confirmed by EP study)
ii. Any cardioversion for AF, AFL or AT (excluding for CTI-dependent flutter)
iii. Use of any Type I or Type III antiarrhythmic medication for the treatment of AF, AFL or AT
c. At any time:
i. Re-ablation for AF, AFL or AT (other than for CTI-dependent flutter)
ii. Use of amiodarone, except intra-procedurally to control an arrhythmia Endpoint status will be assessed through the Month 12 Assessment (Day 360 ± 30).
- PV Diameter change [ Time Frame: 3 months ]Change in pulmonary vein diameter
- Treatment Superiority [ Time Frame: 12 Months ]Treatment Success tested for superiority between the Pulsed Field and Thermal Groups.
- Secondary Effectiveness Endpoint [ Time Frame: 12 Months ]The secondary effectiveness endpoint is the same as the primary effectiveness endpoint but will be tested for superiority rather than non-inferiority. The proportion of Pulsed Field Subjects with Treatment Success will be assessed for superiority to the proportion of Thermal Subjects with Treatment Success.
