REVOLUTION (WFCC-133) - Treatment of Paroxysmal Atrial Fibrillation — REVOLUTION  

Paroxysmal Atrial Fibrillation Clinical Trial

Official title:
REVOLUTION (WFCC-133): Clinical Workflow Study for the Evaluation of the Multi-Electrode Pulmonary Vein Isolation System for the Treatment of Paroxysmal Atrial Fibrillation (PAF)

Clinical Trial Summary

The purpose of this study is to assess the safety and effectiveness of the Circular and Crescent Mapping and Ablation catheters and the workflow of the Multi-Electrode Irrigated Pulmonary Vein Isolation System when used for the treatment of drug refractory symptomatic paroxysmal atrial fibrillation (PAF).

Clinical Trial Description

The study will include a Workflow Phase to verify consistent workflow of all study device components and evaluate acute safety. Upon meeting the defined criteria, the Workflow Phase will be closed and further enrollment will be toward the Main Study Phase which includes the roll-in (the first 3 subjects enrolled at each site following the closure of the Workflow Phase) and Subpopulation Neurological Assessments (SNA) substudy subjects. SNA assessment is a prospective, non-randomized, controlled, acute assessment of two ablation devices to determine if intracerebral microemboli are generated during or immediately after radiofrequency ablation therapy for PAF. SNA subjects will remain and complete the Main Study Phase. However, SNA-control subjects will not be considered part of the Main Study Phase. All subjects, including the subjects enrolled under the Workflow Phase will be included in the Safety Cohort (evaluated for Primary Safety endpoint and all Secondary Safety endpoints). ;
