About this trial

The objective of this feasibility study is to evaluate the safety and effectiveness of the FARAFLEX mapping and pulsed field ablation (PFA) catheter, a novel catheter in treating persistent atrial fibrillation (PersAF) or symptomatic Paroxysmal Atrial Fibrillation (PAF).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥ 18 years of age, or older if required by local law

Symptomatic, documented, Persistent AF or Paroxysmal AF

Willing and capable of providing informed consent

Willing and capable of participating in all follow-up assessments and testing associated with this clinical investigation at an approved clinical investigational center

Disqualifiers

Left atrial anteroposterior diameter ≥ 5.5 cm, or if LA diameter not available, non indexed volume >100 ml (by MRI, CT or TTE report or physician note)

Any prior atrial endocardial, epicardial or surgical ablation procedure for atrial arrhythmia other than ablation for right sided SVT

Current atrial myxoma

Any PV abnormality, stenosis, or stenting (common and middle PVs are admissible)

Trial design

Design model

Parallel

Treatments tested in this trial

  • FARAFLEX Ablation Treatment

    Device

    Subjects scheduled to undergo endocardial mapping and ablation therapy in the treatment of persistent atrial fibrillation or paroxysmal atrial fibrillation. Using the investigational Boston Scientific FARAFLEX Mapping and Pulse Field Ablation (PFA) System, ablation of the pulmonary veins will be performed; ablation of the left atrial posterior wall, mitral isthmus (MI), LA roof line and/or cavo-tricuspid isthmus (CTI) is at the discretion of the investigator.

  • ELEVATE-COR Sub-study

    Device

    Subjects scheduled to undergo endocardial mapping and ablation therapy in the treatment of persistent atrial fibrillation or paroxysmal atrial fibrillation. Using either FARAFLEX™ Mapping and PFA System or a commercially available ablation system, ablation of the pulmonary veins will be performed; ablation of the left atrial posterior wall, mitral isthmus (MI), LA roof line and/or cavo-tricuspid isthmus (CTI) is at the discretion of the investigator, per the selected catheter's IFU and in accordance with the guidelines.

Trial outcomes

Primary outcomes

1

Device or procedure-related Composite Serious Adverse Events (CSAEs)

the incidence of device or procedure-related Composite Serious Adverse Events (CSAEs) following the Index Procedure will be evaluated. Safety analyses will be reported by AF type (Paroxysmal vs. Persistent) and treatment group (FARAFLEX vs. Commercial catheter).

Time frame
Ablation Procedure (Day 0) - Day 7; Day 0- Day 30; Day 0- Day 360
2

Acute Procedural Success

The proportion of subjects that achieve Acute Procedural Success (APS) defined as the percutaneous endocardial creation of a complete, electrically isolating set of lesions around the ostia of the pulmonary veins (PV) and the posterior wall (PW) during the Index Procedure, as clinically assessed by entrance and/or exit block. Effectiveness analyses will be reported by AF type (Paroxysmal vs. Persistent) and treatment group (FARAFLEX vs. Commercial catheter).

Time frame
At the end of the ablation procedure
