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.
