Introduction:
Cavotricuspid isthmus dependent atrial flutter (AFl) is a commonly encountered arrhythmia and a well-recognized risk factor for cardio embolic stroke. Catheter ablation (CA) is the preferred treatment approach for typical AFl due to excellent long-term success. Oral anticoagulation (OAC) therapy is mainstay to reduce stroke risk in patients with AFl, but optimal OAC strategies following successful CA remains unclear. Current guidelines recommend OAC based on established indices of stroke risk such as CHA2DS2VaSC score regardless of the perceived success of ablation1. We sought to examine outcomes of a strategy of OAC discontinuation following successful AFl ablation.
