Medtronic Reveal XT Study

While surgical treatment for atrial fibrillation (AF) has been performed for over 20 years, virtually all of the historical series reported only the recurrence of symptomatic AF and have used only intermittent electrocardiogram (ECG) follow-up. This study compares the use of traditional arrhythmia assessment (ECG and 24-hour holter monitoring) with the use of the Medtronic Reveal XT device to continuously record heart rhythm to quantify postoperative arrhythmia burden following surgical treatment for AF in patients undergoing either lone or concomitant heart surgery.

Condition Intervention Phase
Atrial Fibrillation Device: Reveal XT implantation Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Comparison of Traditional Arrhythmia Assessment With the Use of Continuous Monitoring to Quantify Postoperative Arrhythmia Burden Following Surgical Treatment of Atrial Fibrillation- Medtronic Reveal XT Study

Primary Outcome Measures:
  • Number of ATA (Atrial Tachyarrhythmias) Episodes and Burden, Determined at Defined Postoperative Intervals [ Time Frame: ILR monitoring obtained at 3, 6 and 12 months ]
  • Freedom From Atrial Tachyarrhythmias (ATAs) [ Time Frame: ILR monitoring at 12 months ]

Enrollment: 47
Study Start Date: June 2011
Study Completion Date: January 2016
Primary Completion Date: January 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Reveal XT Device: Reveal XT implantation
The implantation of the Reveal XT device will be performed at the time of surgery before the planned median sternotomy or thoracotomy.
