简要总结

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).

详细描述

The objective of this study is to obtain First-in-Human (FIH) experience with the FARAFLEX mapping and PFA catheter in the treatment of persistent Atrial Fibrillation (persAF) or Paroxysmal Atrial Fibrillation (PAF).

Subjects with symptomatic Persistent Atrial Fibrillation or symptomatic Paroxysmal Atrial Fibrillation will be included in this study.

研究组 & 干预措施

ELEVATE-COR sub-study group

Other

Approximately 50 subjects meeting study eligibility requirements will be enrolled in the sub-study at a subset of centers and randomized to undergo endocardial mapping and ablation in the treatment of persistent atrial fibrillation or paroxysmal atrial fibrillation with either the FARAFLEX™ Mapping and PFA System or a commercially approved ablation system. Subjects will also undergo IVUS imaging of their RCA at the following time points: pre- and post-ablation, 3-Months, 12-Months.

干预措施: ELEVATE-COR Sub-study (Device)

FARAFLEX Treatment group

Other

200 subjects scheduled to undergo endocardial mapping and ablation in the treatment of persistent atrial fibrillation or paroxysmal atrial fibrillation with FARAFLEX mapping PFA catheter and other BSC devices.

干预措施: FARAFLEX Ablation Treatment (Device)

结局指标

主要结局

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

时间窗: Ablation Procedure (Day 0) - Day 7; Day 0- Day 30; Day 0- Day 360

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).

Acute Procedural Success

时间窗: At the end of the ablation procedure

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).
