  Purpose

24 hour Holter monitoring (24HM) is commonly used to assess cardiac rhythm after surgical therapy of atrial fibrillation. This "snapshot" rhythm documentation leaves a large diagnostic window of non recorded atrial arrhythmias and as such a large amount of uncertainty in follow-up result assessment. To improve accuracy of rhythm surveillance thus gaining a more "real-life" scenario of post surgical ablation therapy cardiac rhythm a new insertable cardiac rhythm monitor device (Reveal® XT 9525, Medtronic Inc., Minneapolis, MN, USA) with full observational continuous heart rhythm documentation is implanted.

In order to verify different follow-up strategies after surgical atrial fibrillation therapy, a comparison of different follow-up scenarios (symptoms, different cardiac documentation devices i.e. ECG and 24 hour Holter monitor, at different follow-up time points) is performed intraindividually. Thus the reliability of these devices and follow-up strategies to define success after ablation therapy is evaluated.

Estimated Enrollment: 100
Study Start Date: July 2007
Estimated Study Completion Date: July 2011
Estimated Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Cardiac surgery patients
Patients in atrial fibrillation being scheduled for cardiac surgery and concomitant ablation procedure
Procedure: Cardiac rhythm monitor implantation
post surgical procedure implantation of insertable event recorder for long time heart rhythm surveillance afte ablation therapy
Other Name: Reveal® XT 9525, Medtronic Inc., Minneapolis, MN, USA
Device: Reveal® XT 9525
During cardiac surgery after stand alone or concomitant ablation procedure, an insertable loop recorder will be implanted subcutaneously in left pectoral region. After surgery, patients will be monitored regularly in a quarterly basis by performing telemetry of the device in the outpatient clinic. Furthermore, home telemetry will be performed once a month for optimal heart rhythm observation.
Other Name: Reveal® XT 9525
