Non-vitamin K oral anticoagulants (NOACs) are now widely used as alternatives to warfarin for stroke prevention in atrial fibrillation and management of venous thromboembolism. In clinical practice, there is still widespread uncertainty on how to manage patients on NOACs who bleed or who are at risk for bleeding. Clinical trial data related to NOAC reversal for bleeding and perioperative management are sparse, and recommendations are largely derived from expert opinion. Knowledge of time of last ingestion of the NOAC and renal function is critical to managing these patients given that laboratory measurement is challenging because of the lack of commercially available assays in the United States...

BACKGROUND: New oral anticoagulants (NOACs) have been shown to be comparable to warfarin in patients with non-valvular atrial fibrillation (AF). This meta-analysis was performed to evaluate the efficacy and safety of NOACs for perioperative anticoagulation of AF catheter ablation. METHODS: PubMed, Embase, the Cochrane Library, CNKI, VIP, and SinoMed were searched for articles published up to August 30, 2015. The data were calculated with RevMan 5.2 using a fixed-effects model...

Many patients under oral anticoagulation therapy need percutaneous or surgical interventions/operations. For vitamin K antagonists (VKA), there are recommendations regarding preoperative or postoperative administration. Management of the new oral anticoagulants (NOAC) was supposed to be easier - but some aspects must be considered. Due to the different pharmacokinetic profiles of substances such as dabigatran, rivaroxaban, apixaban, and edoxaban, different recommendations are given.Upon periprocedural management, thromboembolic risk has to be considered in patients treated with NOACs...

Atrial fibrillation (AF), with a prevalence of 1% to 2%, is the most common cardiac arrhythmia. Without antithrombotic treatment, the annual risk of a cardioembolic event is 5% to 6%. The source of a cardioembolic event is a thrombus, which is usually formed in the left atrial appendage (LAA). Prevention of cardioembolic events involves treatment with anticoagulant drugs: either vitamin K antagonists or, recently, novel oral anticoagulants (NOAC). The other (nonpharmacologic) option for the prevention of a cardioembolic event involves interventional occlusion of the LAA...

BACKGROUND: The use of non-vitamin K antagonists (NOACs), uninterrupted (uVKA) and interrupted vitamin K antagonists (iVKA) are common periprocedural oral anticoagulation (OAC) strategies for atrial fibrillation (AF) ablation. Comparative data on complication rates resulting from OAC strategies for solely persistent AF (persAF) undergoing ablation are sparse. Thus, we sought to determine the impact of these OAC strategies on complication rates among patients with persAF undergoing catheter ablation...

Oral anticoagulation (OAC) has been the cornerstone for the prevention of thromboembolic complications in patients with atrial fibrillation (AF) at significant risk of stroke. Catheter ablation is an established efficacious technique for the treatment of AF. Ameliorating the risk of stroke or transient ischaemic attack (TIA) in patients with AF undergoing ablation requires meticulous planning of pharmacotherapy. The advent of non-vitamin K oral anticoagulants (NOACs) has broadened the therapeutic scope, representing a viable alternative to traditional vitamin K antagonists (VKA) in non-valvular AF...

BACKGROUND AND OBJECTIVE: During atrial fibrillation ablation, heparin is required and is guided by the activated clotting time (ACT). Differences in the ACT before ablation and adequate initial heparin dosing in patients receiving non-vitamin K antagonist oral anticoagulants (NOACs) were examined. METHODS: Patients who received warfarin (control, N = 90), dabigatran etexilate (N = 90), rivaroxaban (N = 90) and apixaban (N = 90) were studied. A 100 U/kg dose of heparin was administered as a reliable control dose for warfarin, and the remaining patients were randomly administered 110, 120 or 130 U/kg of heparin in each NOAC group, followed by a continuous heparin infusion...

The novel oral anticoagulants (NOACs) represent a major advance in the treatment of patients with nonvalvular atrial fibrillation and venous thromboembolism (VTE). They have several advantages over vitamin-K antagonists such as warfarin, including more predictable pharmacokinetics and improved safety, particularly with fatal bleeding and intracranial hemorrhage. However, several issues remain surrounding the use of NOACs in certain subpopulations and with the approach to reversal. The periprocedural management of anticoagulation with these relatively new agents can also present several challenges...

BACKGROUND: We previously reported that dabigatran increased the risk of microthromboembolism and hemopericardium compared with warfarin. The safety of non-vitamin-K-antagonist oral anticoagulants (NOACs) in the periprocedural use of atrial fibrillation (AF) ablation is controversial. This study aimed to compare the incidence of asymptomatic cerebral microthromboembolism and hemopericardium in AF ablation among periprocedural use of rivaroxaban, apixaban, and warfarin. METHODS AND RESULTS: This study was a prospective, randomized registry...

INTRODUCTION: Novel oral anticoagulants (NOACs) have been approved for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF). A large number of patients are on NOACs when they present for AF ablation. We intended to evaluate the safety and efficacy of NOACs for AF ablation during the periprocedural period by performing a meta-analysis of trials comparing NOACs with warfarin. METHODS: Studies comparing NOACs (dabigatran and rivaroxaban) with warfarin as periprocedural anticoagulants for AF ablation were identified using an electronic search...

Novel oral anticoagulants (NOACs) are increasingly used in clinical practice, but lack of commercially available reversal agents is a major barrier for mainstream use of these therapies. Specific antidotes to NOACs are under development. Idarucizumab (aDabi-Fab, BI 655075) is a novel humanized mouse monoclonal antibody that binds dabigatran and reverses its anticoagulant effect. In a recent Phase III study (Reversal Effects of Idarucizumab on Active Dabigatran), a 5 g intravenous infusion of idarucizumab resulted in the normalization of dilute thrombin time in 98% and 93% of the two groups studied, with normalization of ecarin-clotting time in 89% and 88% patients...

An increasing number of individuals are on novel oral anticoagulants (NOAC) for anticoagulation instead of vitamin K antagonists (VKA) and roughly 10% of these individuals will require interruption of these agents for procedures annually. Recent evidence surrounding bridging as well as the FDA approval of a new NOAC call for a comprehensive review and update regarding periprocedural NOAC management. The periprocedural management of NOACs involves striking a balance between the risks of bleeding and thromboembolism associated with interruption, bridging, and reinitiation of anticoagulation...
