Objectives This study assessed the incremental benefit of uninterrupted direct oral anticoagulants (DOACs) versus uninterrupted vitamin K antagonists (VKAs) for catheter ablation (CA) of nonvalvular atrial fibrillation (NVAF) on 3 primary outcomes: major bleeding events (MBEs), minor bleeding events, and thromboembolic events (TEs). The secondary outcome was post-procedural silent cerebral infarction (SCI) as detected by brain cardiac magnetic resonance.
Background As a class, evidence of the benefits of DOACs versus VKAs during CA of AF is scant.
Methods A systematic review of Medline, Cochrane, and Embase was done to find all randomized controlled trials in which uninterrupted DOACs were compared against uninterrupted VKAs for CA of NVAF. A fixed-effect model was used, except when I2 was ≥25, in which case, a random effects model was used.
Results The benefit of uninterrupted DOACs over VKAs was analyzed from 6 randomized control trials that enrolled a total of 2,256 patients (male: 72.7%) with NVAF, with significant benefit in MBEs (relative risk [RR]: 0.45; 95% confidence interval [CI]: 0.20 to 0.99; p = 0.05). No significant differences were found in minor bleeding events (RR: 1.12; 95% CI: 0.87 to 1.43; p = 0.39), TEs (RR: 0.75; 95% CI: 0.26 to 2.14; p = 0.59), or post-procedural SCI (RR: 1.09; 95% CI: 0.80 to 1.49; p = 0.58).
Conclusions An uninterrupted DOACs strategy for CA of AF appears to be safer than uninterrupted VKAs with a decreased rate of minor bleeding events. There are no significant differences among the other outcomes. DOACs should be offered as a first-line therapy to patients undergoing CA of AF, due to their lower risk of minor bleeding events, ease of use, and fewer interactions.
