Impact of Type-2 Diabetes Mellitus on the Outcomes of Catheter Ablation of Atrial Fibrillation (European Observational Multicentre Study).

Type-2 diabetes mellitus (DM) is associated with an increased risk of atrial fibrillation (AF). It is unclear whether DM is a risk factor for arrhythmia recurrence following catheter ablation of AF. We performed a nonrandomised, observational study in 7 high-volume European centres.

Catheter ablation for atrial fibrillation on uninterrupted direct oral anticoagulants: A safe approach.

Background: Current consensus guidelines suggest direct oral anticoagulants (DOACs) are interrupted periprocedurally for catheter ablation (CA) of atrial fibrillation (AF). However, this may predispose patients to thromboembolic complications. This study investigates the safety of CA for AF on uninterrupted DOACs compared to uninterrupted warfarin.
