Atrial fibrillation is the most common arrhythmia associated with significant mortality and morbidity secondary to thrombo-embolism. To prevent this thrombo-embolism oral anticoagulation therapy is the recommended treatment. In patients with contraindications to oral anticoagulation therapy, percutaneous left atrial appendage occlusion device is indicated. TEE is essential to guide in all the stages of LAA device deployment. Right from pre-procedure screening, to guiding during deployment, to rule out any complications and post-procedure surveillance and monitoring long term outcomes...

BACKGROUND: Percutaneous catheter-based left atrial appendage closure (LAAC) is a procedure being increasingly performed in patients with atrial fibrillation and high bleeding risk. OBJECTIVE: The purpose of this study was to evaluate the incidence of magnetic resonance imaging (MRI)-detected acute brain lesions (ABLs) as well as potential changes in neurocognitive function after percutaneous LAAC in patients with atrial fibrillation. METHODS: Brain MRI at 3 T was performed within 24 hours before and after LAAC along with neurologic (National Institutes of Health Stroke Scale [NIHSS] score) and cognitive (Montreal Cognitive Assessment [MoCA] test) assessment...

BACKGROUND: We evaluated long-term safety and efficacy of concomitant left atrial appendage (LAA) closure and atrial fibrillation (AF) ablation. METHODS: From February 2013 to June 2017, all patients referred for AF ablation and LAA closure (group 1) were enrolled in the study and compared with a matched control group undergoing AF ablation only (group 2). Pulmonary vein isolation was achieved in all cases with radiofrequency or cryoballoon. LAA was occluded with Watchman or Amplatzer Cardiac Plug or Amulet (ACP) devices...

Atrial fibrillation, a chronic and highly morbid cardiovascular condition which affects over 33 million people worldwide, can be broadly categorized as valvular vs non-valvular in etiology. However, definitions of valvular atrial fibrillation have varied widely in the literature, and there is no clear consensus definition to date. Historically, patients with atrial fibrillation in the setting of rheumatic mitral valve disease have constituted a particularly high risk group for cardioembolic stroke, and for this reason many contemporary trials of pharmaceutical and device therapies for atrial fibrillation have systematically excluded patients with valvular heart disease...

Catheter based left atrial appendage (LAA) closure techniques are emerging as a promising alternative for stroke prevention in patients who cannot tolerate oral anticoagulation. Lariat procedure involves percutaneous catheter based epicardial ligation of the LAA with a suture via an endo-epicardial hybrid approach. It offers the advantage of not leaving behind a focus for thrombus formation or embolization. Similar to surgical ligation of the left atrial appendage, Lariat ligation is limited by leaks in a small percentage of patients...

Left atrial appendage has been shown as a primary source of thrombi in patients with non-valvular atrial fibrillation (AF). Non vitamin k oral anticoagulants (NOAC) have been shown to be safe and effective in the prevention of embolic complications. Current guidelines on AF state that percutaneous left atrial appendage closure (LAAC) might be considered in patients with contraindication to long term oral anticoagulant therapy (OAC). An overview of the main trials on NOAC and LAAC is provided.

BACKGROUND: The LAmbreۛ occluder is a novel device for percutaneous left atrial appendage closure (LAAC). The presented study aimed to report the initial experience in implantation of the novel LAmbre for LAAC in patients with non-valvular AF. METHODS: We conducted a prospective, observational, cohort registry study to evaluate the feasibility of percutaneous LAAC using the LAmbre occlude. RESULTS: Thirty patients (15 female, mean age 77...

Chronic oral anticoagulation therapy is the standard therapy for preventing thromboembolic events in patients with atrial fibrillation. However, oral anticoagulation has been associated with an increased risk of bleeding events, and despite the improvements linked to the introduction of direct oral anticoagulants, more than one third of atrial fibrillation patients still remain untreated. Over the past decade, percutaneous left atrial appendage closure has emerged as a valid alternative to anticoagulation therapy for the prevention of stroke/systemic embolism in patients with atrial fibrillation...

OBJECTIVES: The authors sought to assess the clinical outcomes of left atrial appendage (LAA) closure with the LAmbre closure system in patients with nonvalvular atrial fibrillation (NVAF). BACKGROUND: Over 90% of thrombi are located in the LAA in NVAF patients. METHODS: A prospective, multicenter study was conducted in 153 NVAF patients with CHADS2 score ≥1. RESULTS: The LAA was successfully occluded in 152 patients...

Aims: Long-term results from catheter ablation therapy for atrial fibrillation (AF) remain uncertain and clinical practice guidelines recommend continuation of long-term oral anticoagulation in patients with a high stroke risk. Left atrial appendage closure (LAAC) with Watchman has emerged as an alternative to long-term anticoagulation for patients accepting of the procedural risks. We report on the initial results of combining catheter ablation procedures for AF and LAAC in a multicentre registry...

Atrial fibrillation (AF) is the most common arrhythmia affecting more than 1.6 million patients in Germany. Based on demographic developments, an the number is expected to increase. Embolic strokes in AF patients are particularly severe, and individualized new oral anticoagulant (NOAC) therapy reduces the incidence of stroke in these patients by approximately 70%. Besides vitamin K antagonists, the NOACs rivaroxaban, dabigatran, apixaban, and edoxaban have been introduced into clinical practice; however, major bleeding still occurs at a rate of 2-3% per year...

The left atrial appendage (LAA) has received increasing attention in recent years because of thrombi formation in patients with atrial fibrillation, which increases the risk of stroke. In patients who have contraindications for long-term oral anticoagulation therapy, percutaneous procedures are used to occlude the LAA and there are now several devices available for implantation, both endocardially and epicardially. Despite the high-resolution imaging techniques on hand today, limitations remain in providing information about wall thickness and neighboring structures; therefore, in-depth knowledge of the normal atrial anatomy is mandatory when considering such interventions...

AIMS: Postdeployment mutual orientation between the disk and the lobe in patients undergoing left atrial appendage closure with Amplatzer cardiac plug/Amulet device might impact on the risk of residual leak during follow-up. Thus, we evaluated in an exploratory, pilot study whether the degree of intradevice misalignment, measured by cardiac computed tomography (CT), discriminates the occurrence of peridevice leak in those patients. METHODS: All patients (N = 15) undergoing percutaneous left atrial appendage closure with those specific devices between April 2013 and January 2015 were prospectively included...
