The FARAPULSE PersAFOne III Trial for the Treatment of Persistent Atrial Fibrillation

Prior treatment

• Any of the following cardiac procedures, implants or conditions:
  • Clinically significant arrhythmias other than AF, AFL or AT
  • Hemodynamically significant valvular disease
  • Prosthetic heart valve
  • NYHA Class III or IV CHF
  • Previous endocardial or epicardial ablation or surgery for AF
  • Atrial or ventricular septal defect closure
  • Atrial myxoma
  • Left atrial appendage device or occlusion
  • Pacemaker, implantable cardioverter defibrillator or cardiac resynchronization therapy devices
  • Significant or symptomatic hypotension
  • Bradycardia or chronotropic incompetence
  • History of pericarditis
  • History of rheumatic fever
  • History of congenital heart disease with any residual anatomic or conduction abnormality
• Any of the following within 3 months prior toenrollment:
  • Myocardial infarction
  • Unstable angina
  • Percutaneous coronary intervention
  • Heart surgery (e.g. coronary artery bypass grafting, ventriculotomy, atriotomy)
  • Heart failure hospitalization
  • Stroke or TIA
  • Clinically significant bleeding
  • Pericarditis or pericardial effusion
  • Left atrial thrombus

Other illness

• AF that is:
  • Paroxysmal (longest AF episode \< 7days)
  • Longstanding (has persisted \> 12 months or that does not respond to cardioversion if \< 12 months)
  • Secondary to electrolyte imbalance, thyroid disease, alcohol abuse or other reversible / non-cardiac causes
• History of blood clotting or bleeding abnormalities.
• Clinically significant psychological condition that in the investigator's opinion would prohibit the subject's ability to meet the protocol requirements

Lab values

• Medical conditions that would prevent participation in the study, interfere with assessment or therapy, significantly raise the risk of study participation, or confound data or its interpretation, including but not limited to
  • Body mass index (BMI) \> 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

Other

• Subjects will be excluded from participating in this study if they meet any one of the following exclusion criteria:
• Left atrial anteroposterior diameter ≥ 5.5 cm as documented by transthoracic echocardiography (TTE) or computed tomography (CT)
• Contraindication to, or unwillingness to use, systemic anticoagulation
• Contraindications to CT or MRI
• Sensitivity to contrast media not controlled by premedication
• Women of childbearing potential who are pregnant, lactating or not using birth control
• 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.
  • \-

  • 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.
• Patient participation requirements:
  • Lives locally
