Device: THERMOCOOL® SMARTTOUCH™ Catheter
Registration Number
NCT01639495
Lead Sponsor
Biosense Webster, Inc.
Brief Summary

This is a prospective, multicenter, non-randomized continued access clinical evaluation utilizing the THERMOCOOL® SMARTTOUCH™ catheter.

Detailed Description

The device is currently under investigation with IDE #G110030. This continued access study will enroll subjects that have participated in the Smart-AF IDE study. Subjects with drug refractory symptomatic paroxysmal atrial fibrillation (PAF) will be considered for this study. Effectiveness and safety endpoints have been defined and will be evaluated post treatment.

Primary Outcome Measures
NameTimeMethod
Incidence of Primary Adverse Events Within Specified Study Period12 months post procedure

Primary safety endpoint consists of primary adverse events (AE) within 7 days post procedure Or pulmonary vein stenosis and atrio-esophageal fistula events that occurred within 12 months post-procedure. Primary adverse events include death, myocardial infarction, pulmonary vein stenosis, diaphragmatic paralysis, atrio-esophageal fistula, transient ischemic attack, stroke / cerebrovascular accident, thromboembolism, pericarditis, cardiac tamponade, pericardial effusion, pneumothorax, atrial perforation, vascular access complications, pulmonary edema, initial and prolonged hospitalization (excluding those due to pre-existing arrhythmia recurrence), heart block.

Percentage of Subjects Achieved Freedom From Atrial TachyarrhythmiasDay 91-361

Freedom from documented symptomatic atrial fibrillation/atrial tachycardia/atrial flutter (hereinafter collectively referred to as "atrial tachyarrhythmias") based on electrocardiographic data during the effectiveness evaluation period (Day 91-361). Acute procedure failures, antiarrhythmic drug(AAD) changes and repeat ablation occurring during evaluation period were deemed as primary effectiveness failures

Secondary Outcome Measures
NameTimeMethod
Late Onset Serious Adverse EventsFrom 31 days post procedure to month 12

Late onset serious adverse events (SAEs) are those non-primary SAEs occurred after 31 days post procedure

Peri-procedural Serious Adverse EventsWithin 8-30 days post procedure

Peri-procedural serious adverse events (SAEs) are those non-primary SAEs occurred within 8-30 days post procedure

Percentage of Subjects Achieved Acute Effectiveness5 hours of procedure time

Acute effectivenesss is defined as confirmation of entrance block into all Pulmonary veins
