Summary

The objective of this safety and feasibility study is to assess whether the endocardial creation of electrically nonconductive lesions via PEF catheter ablation applied using the FARAPULSE Pulsed Field Ablation System Plus-PersAF is a feasible and safe treatment for PersAF and associated AFL

  • Holter within 90 days prior to the Enrollment Date demonstrating 24 hours of continuous AF
  • Patients who are ≥ 18 and ≤ 75 years of age on the day of enrollment.

Exclusion Criteria

Subjects will be excluded from participating in this study if they meet any one of the following exclusion criteria:

  • AF that is:
  • Paroxysmal (longest AF episode 12 months or that does not respond to cardioversion if 40
  • Solid organ or hematologic transplant, or currently being evaluated for an organ transplant
  • Severe lung disease, pulmonary hypertension, or any lung disease involving abnormal blood gases or significant dyspnea
  • Renal insufficiency with an estimated creatinine clearance <30 mL/min/1.73 m2, or any history of renal dialysis or renal transplant
  • Active malignancy or history of treated cancer within 24 months of enrollment
  • Clinically significant gastrointestinal problems involving the esophagus, stomach and/or untreated acid reflux
  • Clinically significant infection
  • Predicted life expectancy less than one year
  • Clinically significant psychological condition that in the investigator's opinion would prohibit the subject's ability to meet the protocol requirements
  • Current or anticipated enrollment in any other clinical study
  • Employment by FARAPULSE or the same hospital department or office of any investigator, or a family member of any of the preceding groups.
  • Use of amiodarone after day of index ablation procedure. Patients will cease use of amiodarone on or before the date of the index ablation procedure.
