Aims Non-vitamin K antagonist oral anticoagulants (NOAC) have been shown to be safe and effective alternatives to warfarin for the prevention of thromboembolic complications in patients with non-valvular atrial fibrillation (AF). The aim of this study was to investigate the complications and the use of NOACs in AF patients undergoing elective cardioversion. Methods and results This nationwide multicentre study included consecutive elective cardioversions in AF patients treated with NOACs between October 2011 and May 2016. Data on patient characteristics, antithrombotic treatment and acute (<30 days) complications were collected. One thousand twenty-one patients (mean age 64 years, 70% men) underwent 1291 elective cardioversions, of which 680 (52.7%) cardioversions were performed in patients using dabigatran, 431 (33.4%) rivaroxaban, and 159 (12.3%) apixaban. Mean CHA(2)DS(2)-VASc score was 1.8 (+/- 1.5). A total of 3 thromboembolic events occurred after the cardioversion (0.2%): 1 patient receiving dabigatran experienced an ischaemic stroke on Day 2 and 1 rivaroxaban treated patient on Day 4. One patient receiving dabigatran experienced a transient ischaemic attack on Day 11. All 3 patients had used recommended doses of the NOAC. A total of 6 (0.5%) clinically relevant, but not serious bleeding events occurred. Only short duration of AF was associated with lower rate of AF recurrence. Conclusion Thrombotic and bleeding complications related to NOACs were uncommon (<0.5%) in real life AF patients undergoing elective cardioversion.
