Brief Summary
Postoperative atrial fibrillation and atrial flutter (POAF) is the most common complication after cardiac surgery requiring intervention or prolonged hospital stay. POAF is associated with higher mortality and higher risk of thromboembolic events. However, It is yet unknown whether a now event of postoperative atrial fibrillation is an indication of a chronic arrhythmic disease - a tendency towards developing recurrent atrial fibrillation or merely a response to the stress of surgery with not recurrence. This distinction is critical to determine the appropriate therapy. Since recurred events of atrial fibrillation (Paroxysmal atrial fibrillation) are associated with long term risk for stroke and thromboembolic evens patients with PAF are treated with long term anticoagulation. Missing the long term recurrence of arrhythmia may result in under-treatment and pose a significant risk of stroke. Bio-Monitor is a subcutaneous implanted device that automatically detects arrhythmias and stores electrocardiogram (ECG) recordings. It will enable the detection of atrial fibrillation over a period of years and allow correct diagnosis and appropriate treatment. The purpose of the study is to study the long term behavior of POAF, determine the likelihood of developing paroxysmal atrial fibrillation in patients with POAF and to define the risk factors for this eventuality

Study Arms (2)
BioMonitor
ACTIVE COMPARATORParticipants randomized for this arm will be implanted with a BioMonitor device an implantable loop recorder inserted under the skin in the region of the thorax. It continuously records heart rhythm for a period of up to 7 years. The device will be interrogated at 1 month intervals. All arrhythmic events and conductive disturbances will be noted. In addition will be followed as specified in the standard arm
Standard
ACTIVE COMPARATORParticipants randomized for this arm will be followed by biannual office visits initialing clinical evaluation, review of clinical events, review and update of medical therapy. Participants will undergo ECG holter examination at 3 and 6 months after discharge
Interventions
Implantation of a BioMonitor device and continuously monitoring heart rhythm for study duration
Eligibility Criteria
You may qualify if:

- cardiac surgery during index hospitalization, including (CABG, valvular replacement or repair, a combination) without Maze procedure
- CHA2DS2-VASc≥2
- Sinus rhythm at the time of BioMonitor implantation or definite intention to cardiovert prior to discharge
- Signed Informed Consent
You may not qualify if:
- History of atrial fibrillation/flutter prior to cardiac surgery
- Contraindication for anticoagulation therapy
- Dual chamber pacemaker or ICD implanted or planned
- Active systemic infection
- Another (non-AF) indication for long term anticoagulation
- Maze procedure
- Inability to attend scheduled, periodic office visits for follow-up
