Catheter ablation (CA) of atrial fibrillation and flutter is associated with a high risk of both perioperative thromboembolic events and bleeding. Adequate anticoagulation is imperative to reduce the risk of complications. The aim of this review was to analyze modern approaches to anticoagulant therapy for CA of atrial fibrillation and flutter, as well as provide practical information based on a comparison of current guidelines and evidence base. The search for literature sources on anticoagulant therapy in CA was carried out in the PubMed, Scopus, Web of Science databases. The results of key randomized trials and meta-analyzes are presented, and a comparison of current Russian and international guidelines is given. Unresolved issues requiring further research are discussed.

Abstract: The significantly increased incidence of stroke and systemic embolisation caused by atrial fibrillation can be prevented by adequately adjusted anticoagulant therapy. Vitamin K antagonists effectively decrease the risk of thromboembolic events but this effect is influenced by many factors. The development of the new direct oral anticoagulant drugs (DOAC) in the last few years provided new opportunities for us to choose the suitable anticoagulant therapy. According to the results of the ENGAGE AF–TIMI 48 and ENSURE-AF multicenter, randomized trials, edoxaban, the recently introduced DOAC is equally effective as the traditional coumarin therapy, nevertheless, it ensures more tolerable anticoagulation for patients suffering from non-valvular atrial fibrillation.

Atrial fibrillation is a risk factor for ischemic stroke. To prevent stroke oral anticoagulants can be administered. Old and new types of anticoagulants are available. Nowadays, old type, acenocumarol based anticoagulants are used preferentially in Hungary. Aim: The advantages and the disadvantages of anticoagulants are well known, but anticoagulants are underused in many cases. Method: The authors retrospectively examined how frequent atrial fibrillation was and whether the usage of anticoagulants in practice was in accordance with current guidelines among acute stroke cases admitted to the Department of Neurology, Medical and Health Science Centre of Debrecen University in 2009. Results: Of the 461 acute stroke cases, 96 patients had known and 22 patients had newly discovered atrial fibrillation. Half of the patients did not receive proper anticoagulation. Only 8.4% of them had their INR levels within the therapeutic range. Conclusions: The findings are similar to those reported in other studies. Many factors may contribute to the high proportion of improper use of anticoagulants, and further investigations are needed to determine these factors. In any case, elimination of these factors leading to a failure of anticoagulation may decrease the incidence of stroke. Orv. Hetil., 2012, 153, 732–736.

Hemorrhagic Events

Trans-catheter ablation of atrial fibrillation (AF) is a common treatment for symptomatic AF. Among the major complications of AF ablation are stroke, transient ischemic attacks and peri-procedural cardiac tamponade. Various clinical trials have shown that uninterrupted treatment with vitamin K antagonists (VKA) is associated with a lower incidence of embolic events compared to discontinuation of therapy; until recently, in the absence of equally solid evidence, this practice was not extended to the new oral anticoagulants (NOAC) not VKA due to the fear of hemorrhagic complications potentially associated with the use of an "irreversible" anticoagulant. The case of a patient suffering from numerous comorbidities is reported here. In light of the poor response to anti-arrhythmics, a TC-RF ablation was performed, with suspension of dabigatran administration only on the day of the procedure (for a total period <24 hours). Although the fear of the risk of bleeding potentially associated with the trans-catheter ablation procedure may still induce clinicians to stop anticoagulant therapy, even the decision to discontinue anticoagulant therapy with dabigatran on the day of surgery alone is challenged by recent evidence in the literature supporting the efficacy of dabigatran in reducing the incidence of hemorrhagic events during and after ablation, including the results of the RE-CIRCUIT study (Cardiology)

Maintain Sinus Rhythm

Abstract Atrial fibrillation (AF) and heart failure with reduced ejection fraction (HFrEF) are two conditions that frequently impact reciprocally on each other. Patients with HFrEF have an increased risk of stroke, hospitalization and mortality after they develop AF and vice versa, AF causing deterioration of the ejection fraction is also associated to increased mortality. Catheter ablation has emerged as an effective alternative to antiarrhythmic drug treatment to maintain sinus rhythm and some randomized trials have shown a potential benefit in terms of mortality and hospitalization. This review discusses the available evidence regarding catheter ablation treatment in this specific patient group.
