NAVISTAR® THERMOCOOL® SF Catheter: Observational Study

Completed
Conditions
Atrial Fibrillation
Paroxysmal Arrhythmia
Interventions
Device: Catheter Ablation (NAVISTAR® THERMOCOOL® SF Catheter)
Registration Number
NCT01585961
Lead Sponsor
Biosense Webster, Inc.
Brief Summary

This is a prospective, interventional, observational, unblinded, single-arm, multicenter registry of younger and older subjects with drug refractory, recurrent, symptomatic paroxysmal atrial fibrillation.

Detailed Description

This study is to measure the "real-world" acute procedural outcomes (procedural efficiency, acute safety, and effectiveness at one year) associated with use of the NAVISTAR® THERMOCOOL® SF Catheter in a clinical setting in subjects with drug refractory, recurrent symptomatic paroxysmal atrial fibrillation.

Catheter AblationCatheter Ablation (NAVISTAR® THERMOCOOL® SF Catheter)These patients have drug refractory, recurrent, symptomatic paroxysmal atrial fibrillation, are aged 18 years or older, and have provided written informed consent to participate in the study, including consent to undergo catheter ablation with the study device.
Primary Outcome Measures
NameTimeMethod
Total Procedure TimeDay 0 (procedure)
Acute Procedural SuccessDay 0 (procedure)

Confirmation of entrance and/or exit block across all targeted pulmonary veins.

Total Fluoroscopy TimeDay 0 (procedure)

The fluoroscopy time will be measured for each phase (access, mapping, ablation, and validation) of the procedure and summed to derive the total time.

Secondary Outcome Measures
NameTimeMethod
Fluid Volume Delivered Via Ablation CatheterDay 0 (procedure)
Change in Atrial Fibrillation Effect on Quality of Life (AFEQT) Total ScoreScreening to 12 Month Visit

Change is calculated as 12 month overall AFEQT score minus score at screening. An overall AFEQT score ranges from 0 to 100. A score of 0 corresponds to complete disability (or responding "extremely" limited, difficult or bothersome to all questions answered), while a score of 100 corresponds to no disability (or responding "not at all" limited, difficult or bothersome to all questions answered). Therefore a positive change in score corresponds to improvement in AF symptoms.

Total Radiofrequency (RF) TimeDay 0 (procedure)

Total RF time is defined as the total time that RF energy is delivered during the procedure.

Number of Patients With Inpatient Hospital Visit(s) Related to Atrial Fibrillation12 Month Visit
Number of Patients With Repeat Ablations1 year
Number of Subjects With Lost Work Days, Related to AF, at 12 Month Visit12 Month Visit
Mean Number of Radiofrequency (RF) ApplicationsDay 0 (procedure)

RF applications is defined as the number of times RF energy is delivered during the procedure.

Post-procedure AF Symptoms12 Month Visit

Symptoms attributed to paroxysmal atrial fibrillation reported at 12 month visit

Number of Patients With Outpatient Emergency Visits Related to Atrial Fibrillation12 Month Visit
