Implantable loop recorder for augmenting detection of new-onset atrial fibrillation after typical atrial flutter ablation.

Background: Patients with typical atrial flutter (AFL) undergoing successful cavotricuspid isthmus ablation remain at risk for future development of new-onset atrial fibrillation (AF). Conventional monitoring (CM) techniques have shown AF incidence rates of 18%-50% in these patients.

Objectives: To evaluate whether continuous monitoring using implantable loop recorders (ILRs) would enhance AF detection in this patient population.
