BACKGROUND: Periprocedural anticoagulation is important in catheter ablation (CA) of atrial fibrillation (AF) and there is increasing evidence that uninterrupted vitamin K antagonist (VKA) therapy is superior to interrupted anticoagulation strategies. Since the emergence of direct oral anticoagulants (DOACs), numerous studies have shown promising results for their use in uninterrupted strategies. However, further studies are needed to further define the efficacy and safety of performing AF ablation with uninterrupted factor XA inhibitors or direct thrombin inhibitors.
METHODS AND RESULTS: We have performed CA of AF without discontinuation of either VKA or DOAC therapy since April 2014. A total of 376 patients with AF underwent CA including pulmonary vein isolation. All of the patients were divided into 2 groups (uninterrupted VKA or uninterrupted DOACs). Anticoagulation with DOACs was associated with fewer complications than uninterrupted VKA therapy (P=0.04). There were significant differences between groups in the rates of congestive heart failure, left ventricular ejection fraction, body weight, and estimated glomerular filtration rate and of the CHADS2, CHA2DS2-VASc and HAS-BLED scores. Therefore, we also analyzed the results using the propensity score-matching method. We found no significant difference in periprocedural complications between uninterrupted VKA or DOACs therapy (P=0.65).
CONCLUSIONS: CA of AF without discontinuation of DOACs is not inferior to CA without discontinuation of a VKA, with regard to ischemic or hemorrhagic complications.
