NCT01176617

Brief Summary

The purpose of this study is to determine if continuous monitoring using an implantable loop recorder (ie. a device that is placed just underneath the skin of the chest and monitors the heart rate and rhythm) for a year long period after atrial fibrillation ablation may be superior to the current conventional monitoring strategy used by us for determination of atrial fibrillation recurrence (ie. return of the abnormal heart rhythm) and/or arrythmia burden (ie. how long the abnormal rhythm continues or how often the rhythm occurs). Some data suggests that continuous monitoring over longer periods may be better in identifying recurrence of atrial fibrillation after ablation and thus assist in its overall management. The device being used for this study is the Reveal XT, which, is currently FDA approved for monitoring all varieties of cardiac rhythm disorders including atrial fibrillation.

Outcome Measures

Primary Outcomes (1)

  • Arrhythmia Burden

    The primary outcome will be arrhythmia recurrences (atrial fibrillation and/or other atrial arrhythmias) after atrial fibrillation ablation over the initial 6 months and one year post-ablation as detected by the implantable loop recorder versus the conventional monitoring strategy. Months 1- 6 patients were being monitored by CM and ILR and in months 6 - 12 they were randomized to either ILR or CM.

    6 and 12 months

Secondary Outcomes (1)

  • Detection of Actionable Events Resulting in Change of Clinical Care

    12 months

Study Arms (2)

Conventional Monitoring Strategy

NO INTERVENTION

Subjects will be monitored for 12 months using the conventional strategy which includes wearing a monitor over 3 separate 30-day periods over the first year post-ablation and daily pulse checks.

Reveal XT

OTHER

Subjects will be monitored using the conventional monitoring strategy for the first 6 months post-ablation. During the next 6 months, subjects will be monitored using the data from the Reveal device, transmitted from home every 30 days.

Device: Reveal XT implantable loop recorder

Interventions

All study participants will receive the Reveal XT implantable loop recorder immediately after completion of the ablation procedure.
