BACKGROUND: Interventional closure of the left atrial appendage (LAA) in patients with non-valvular atrial fibrillation, high thromboembolic and bleeding risk or bleeding history is an alternative therapeutic strategy to oral anticoagulation. It is not known if the exclusion of the LAA from the blood circulation affects the left atrial volume (LAV) and consequently its prognostic value or the circulatory performance of the heart in humans. METHODS: We aimed to prospectively assess potential changes in baseline LAV, left ventricular ejection fraction (LVEF), NT-proBNP-level and the covered distance in the 6-min walk-test 6 weeks and 6 months after LAA closure with the WATCHMAN™ device...

Accurate assessment of the left atrial appendage (LAA) is important for pre-procedure planning when utilizing device closure for stroke reduction. Sizing is traditionally done with transesophageal echocardiography (TEE) but this is not always precise. Three-dimensional (3D) printing of the LAA may be more accurate. 24 patients underwent Watchman device (WD) implantation (71 ± 11 years, 42% female). All had complete 2-dimensional TEE. Fourteen also had cardiac computed tomography (CCT) with 3D printing to produce a latex model of the LAA for pre-procedure planning...

The increasing prevalence of atrial fibrillation with the aging population and its associated major morbidity and mortality due to thromboembolic stroke have resulted in intensive research on stroke prevention or stroke risk reduction strategies. Several surgical techniques for left atrial appendage (LAA) occlusion have evolved over the past decades. Surgeons have been using different techniques leading to highly variable and, in particular, poor data on outcomes. LAA closure is performed either as a concomitant procedure during open-heart surgery or as a stand-alone surgical procedure as part of minimally invasive (mini-thoracotomy or thoracoscopy) arrhythmia surgery...

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...

Nonvalvular atrial fibrillation (AF) is the most common arrhythmia with a prevalence of 1-2% and affects approximately 15-20% of all octogenarians. Patients are at increased risk of thromboembolic stroke, with an overall risk of 5% per year. Thrombi form almost exclusively in the left atrial appendage (LAA), a blind sac-like heterogeneous structure trabeculated by pectinate muscles. In the past five decades, life-long oral anticoagulation (OAC) with vitamin K antagonists (VKA) has been the state-of-the art treatment to prevent stroke and systemic embolism from thrombi in AF...

Atrial fibrillation (AF) is associated with an increased risk of stroke and thromboembolism (TE). The WATCHMAN(TM) left atrial appendage (LAA) closure device is indicated to reduce the risk of TE from the LAA in patients with non-valvular AF. Here, we present a case of a patient with device-related thrombus who suffered a TE event two months after WATCHMAN(TM) LAA closure and two weeks after switching from aspirin plus warfarin to aspirin plus clopidogrel therapy. Laboratory investigation identified the patient to be hypercoagulable and to be a non-responder to clopidogrel therapy...

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...

There has not been much progress in the development of transcatheter tricuspid valves to treat tricuspid regurgitation because of the difficulty in anchoring a stented valve onto the complex tricuspid annulus. Hence, the concept of heterotopic implantation of the transcatheter tricuspid valve onto the cavo-atrial junction was proposed. However, to date there has been no detailed in vitro investigation of the hemodynamic performance of this new device. The study utilises both 2-D and 3-D particle image velocimetry (PIV) to interrogate the flow patterns in the vicinity of the extra-cardiac tricuspid valves in an in vitro physiological flow loop, specifically at four measurement locations in the cavo-atrial anatomy...
