The objective of the ADVANTAGE AF Study is to establish the safety and effectiveness of the FARAPULSE Pulsed Field Ablation System (FARAPULSE PFA System) for treatment of drug resistant, symptomatic persistent atrial fibrillation (PersAF).

You can join if…

Open to people ages 18 years and up

  1. Age ≥ 18 years of age, or older if specified by local law
  2. Subjects have symptomatic, documented, drug-resistant, Persistent AF, defined as:
    1. Documented: at a minimum a physician's note confirming the arrhythmia symptoms and durations AND, within 180 days of Enrollment Date, either: i. A 24-hour continuous ECG recording confirming continuous AF OR ii. Two ECGs from any regulatory cleared rhythm monitoring device showing continuous AF taken at least 7 days apart b.

  7. Patients who have not been on anticoagulation therapy for at least 4 weeks prior to the ablation procedure
  8. Women of childbearing potential who are pregnant, lactating, not using medical birth control or who are planning to become pregnant during the anticipated study period
  9. Health conditions that in the investigator's medical opinion would prevent participation in the study, interfere with assessment or therapy, significantly raise the risk of study participation, or modify outcome data or its interpretation, including but not limited to:
    1. Body Mass Index (BMI) > 42.0
    2. Solid organ or hematologic transplant, or currently being evaluated for a transplant
