CS1543: PersAFOne III: Feasibility Study of the FARAPULSE Pulsed Field Ablation System Plus - PersAF in the Treatment of Persistent Atrial Fibrillation
Study Details
Study Description
Brief 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

Detailed Description
PersAFOne III study is a prospective, multi-center safety and feasibility study in subjects with persistent AF. Subjects will undergo percutaneous PEF ablation for pulmonary vein isolation as well as cavotricuspid isthmus interruption and other left atrial ablations at the investigator's discretion. Subjects will then be followed at 30 days, 60 ± 15 days, 6 months and 12 months for adverse events, recurrence of arrhythmia after a 90 day blanking period and other relevant outcome measures.

Outcome Measures
Primary Outcome Measures
- Composite Safety Endpoint (CSE) defined as the incidence of the following early-onset and late-onset serious adverse events (SAEs) which are device- or procedure-related, as adjudicated by the CEDMC [30-Days]
Proportion of Intent to Treat subjects with one or more of the specified device or procedure related SAEs Endpoint(CSE) defined as the incidence of the following early-onset serious adverse events (SAEs) which are device- or procedure-related, as adjudicated by the Clinical Events and Data Monitoring Committee (CEDMC). Atrioesophageal fistula and PV stenosis components will be assessed for occurrence at any time during follow-up. Early onset (within 30 days of an Index or Remap Procedure) Death Myocardial infarction (MI) Persistent diaphragmatic paralysis Stroke or transient ischemic attack (TIA) Peripheral or organ thromboembolism Pericarditis Cardiac tamponade / perforation Vascular access complications requiring intervention Heart block Late onset (any time during follow-up through 12 months) Pulmonary vein (PV) stenosis (> 70% diameter reduction from baseline) Atrio-esophageal fistula
Secondary Outcome Measures
- The Primary Safety Endpoint assessed at 7 days [7-Days]
Proportion of Intent to Treat subjects with one or more of the specified device or procedure related SAEs Endpoint(CSE) defined as the incidence of the following early-onset serious adverse events (SAEs) which are device- or procedure-related, as adjudicated by the Clinical Events and Data Monitoring Committee (CEDMC). Atrioesophageal fistula and PV stenosis components will be assessed for occurrence at any time during follow-up. Early onset (within 30 days of an Index or Remap Procedure) Death Myocardial infarction (MI) Persistent diaphragmatic paralysis Stroke or transient ischemic attack (TIA) Peripheral or organ thromboembolism Pericarditis Cardiac tamponade / perforation Vascular access complications requiring intervention Heart block Late onset (any time during follow-up through 12 months) Pulmonary vein (PV) stenosis (> 70% diameter reduction from baseline) Atrio-esophageal fistula
- The proportion of subjects with a device- or procedure-related SAE [12 Months]
Proportion of subjects with one or more device or procedure related SAEs.
- The proportion of subjects with stroke or TIA [12 Months]
The proportion of subjects with stroke or TIA
- The proportion of subjects requiring cardioversions [12 Months]
The proportion of subjects requiring cardioversions
- The proportion of subjects requiring an arrhythmia-related (AF, AFL or AT) hospitalization [12 Months]
The proportion of subjects requiring an arrhythmia-related (AF, AFL or AT) hospitalization
Other Outcome Measures
- Acute Procedural Success [12 months]
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 (PVI) using the FARAPULSE Pulsed Field Ablation System Plus-PersAF during the Index Procedure, as clinically assessed by entrance and/or exit block performed ≥ 20 minutes after the last PVI lesion is made.
