Abstract
ABSTRACTIntroduction: Long-term cessation of oral anticoagulation (OAC) following successful catheter or surgical ablation of atrial fibrillation (AF) is debated. Usually, in the presence of sinus rhythm at serial ECG recordings, the CHADS2, CHA2DS2VASc, and HAS-BLED scores are adopted to guide decision regarding OAC management.Areas covered: The safety of OAC cessation in patients without recurrent AF but with historically elevated risk for thromboembolism remains largely unknown. Taking the cue from two clinical cases, we provide an updated summary of the latest evidence regarding how to manage OAC after a successful atrial fibrillation ablation.Expert commentary: The present clinical perspective suggests that, at least within patients with severely enlarged left atrium, previous cardiac surgery and catheter or surgical AF ablation, especially if repeated, assessment of atrial contractility by transthoracic echocardiography should be performed before discontinuing OAC in patients who maintain sinus rhythm, confirmed by serial ECG or Holter monitorings.
