T Maurer, C Sohns
In patients suffering from atrial fibrillation (AF), modern antithrombotic therapy and anticoagulation strategies should be individualized based on shared decision making including patient preferences and the absolute and relative risks of stroke and bleeding. Estimation of the individual risk for stroke is still based on the CHA2DS2-VASc score. Based on the most recent guidelines for the management of AF, oral anticoagulation therapy should be considered for men with a CHA2DS2-VASc score ≥1 and women with a score ≥2, balancing the expected stroke reduction, risk of bleeding and patient preference...

BACKGROUND: Catheter and surgical ablation of atrial fibrillation (AF) can be associated with a risk of thromboembolic events. The goal of this study was to assess optimal anticoagulation management during thoracoscopic ablation of AF. METHODS: Fifty-two patients with persistent or long-standing persistent AF underwent hybrid ablation consisting of thoracoscopic ablation followed by electrophysiologic (EP) evaluation and consecutive ablation if indicated. The thoracoscopic ablation was performed using three different anticoagulation protocols: (1) without periprocedural heparin and without occlusion of the left atrial appendage; (2) with periprocedural heparin but without left atrial appendage occlusion; and (3) with periprocedural heparin and left atrial appendage occlusion...

The left atrial appendage (LAA) is an extension originating from the body of the left atrium. The LAA is derived from the primary atrium and shows anatomical and physiological deviations from the left atrium. Different LAA morphologies exist. The LAA is not only the most frequent origin of intracardiac thrombi, it also frequently shows triggers responsible for the initiation or maintenance of atrial tachyarrhythmia and atrial fibrillation (AF). Isolation of the LAA using radiofrequency energy in addition to isolation of the pulmonary vein has recently gained importance due to the potential for increasing the clinical success rates, particularly in patients with persistent and long-standing persistent AF; however, after LAA isolation the incidence of LAA thrombi and systemic thromboembolisms might be increased even under treatment with oral anticoagulants, depending on the ablation strategy used...

OBJECTIVES: Concomitant surgical ablation of atrial fibrillation (AF) is recommended for patients undergoing off-pump coronary revascularization in the presence of this arrhythmia. Achievement of optimal visualization of pulmonary veins while maintaining stable haemodynamic conditions is crucial for proper completion of the ablation procedure. This study evaluates the safety and feasibility of right atrial positioning using a suction-based cardiac positioner as opposed to compressive manoeuvres for exposure during off-pump surgical ablation for AF...

BACKGROUND: The aim of this study was to compare treatment of moderate to severe symptomatic mitral regurgitation (MR) with either conventional surgery or the mitral valve edge-to-edge device (MitraClip®) in very elderly patients. The newly introduced MitraClip device has demonstrated promising acute results in treating this patient cohort. Also noteworthy is the fact that patients who otherwise would have been denied surgery are increasingly referred for treatment with the MitraClip device...

Cardiovascular disease encompasses coronary artery disease and valvular heart disease, and the prevalence of both increases with age. Over the past decade, the landscape of interventional cardiology has evolved to encompass a new set of percutaneous procedures outside the coronary tree, including transcatheter aortic valve implantation, transcatheter mitral valve repair, and left atrial appendage occlusion. These interventions have sparked a new discipline within interventional cardiology referred to as structural heart disease (SHD) intervention...

Atrial fibrillation (AF) remains an important clinical problem with severe complications such as stroke, which especially harms those with risk factors as calculated by the CHADS2 or CHA2DS2-VASc. Until now, no therapy has proven 100% effective against AF. Since the left atrial appendage (LAA) is the most prominent nonvalvular AF-related thromboembolic source and (novel) oral anticoagulant [(N)OAC] carries the hazard of bleeding, LAA occlusion may be an alternative, especially in patients who are ineligible for (N)OAC therapy...

Non-valvular atrial fibrillation is associated with a significantly increased risk of embolic stroke due to blood clot forming predominantly in the left atrial appendage (LAA). Preventive measures to avoid embolic events are permanent administration of anticoagulants or surgical closure of the LAA. Various clinical trials provide evidence about safety, effectiveness and therapeutic success of LAA occlusion using various cardiac occluder devices. The use of such implants for interventional closure of the LAA is likely to become a valuable alternative for stroke prevention, especially in patients with contraindication for oral anticoagulation as safety, clinical benefit and cost-effectiveness of LAA occlusion has recently been demonstrated...

Ischemic stroke is a common complication of atrial fibrillation. Currently, oral anticoagulant drugs are the most commonly used method of stroke prevention. Left atrial appendage occlusion is thought to be the main source of thrombi in patients with AF. Percutaneous left atrial appendage is a valuable therapeutic option for selected high-risk patients with AF and contraindications for oral anticoagulation therapy. While complete closure of the left atrial appendage is the goal of a device implantation the variable nature of the left atrial appendage anatomy makes this goal difficult to achieve...

INTRODUCTION: Atrial fibrillation (AFib) is related to a high risk of stroke. The main role in etiopathogenesis is played by the left atrial appendage (LAA). As many as 95 % of thrombi in nonvalvular atrial fibrillation are located in the appendage. Prevention of stroke then consists in permanent anticoagulation which, however, has its limits and risks. An alternative method is the left atrial appendage occlusion. In our report, we would like to present a new possibility of the closure using the epicardial system AtriClip (AtriCure)...

INTRODUCTION: Atrial fibrillation (AF) is one of the leading causes of stroke. Risks associated with oral anticoagulation limit adherence to recommended therapy. Left atrial appendage (LAA) occlusion is a treatment alternative in patients with AF. We performed a network meta-analysis (NMA) of randomized trials evaluating the efficacy of LAA occlusion compared with oral anticoagulant, antiplatelet, and placebo for stroke prevention. We also assessed the impact of LAA occlusion on mortality, major bleeding, and operative time...

: International guidelines indicate that interventional closure of left atrial appendage and patent foramen ovale may be considered in selected patients for stroke prevention. These procedures appear, however, from the published literature, at high risk of uselessness and futility in the single case, if not even capable to induce harm and adverse events. In fact, all reported systematic reviews and meta-analyses have not shown in a convincing manner the superiority of these procedures in stroke prevention, taking into account the occurrence of possible complications also, as compared with alternative medical treatment...
