recommendations! Published in 2017 at "Herz"

DOI: 10.1007/s00059-017-4559-0

Abstract: ZusammenfassungDas linke Vorhofohr (LAA) ist eine Ausstülpung aus dem linken Vorhof (LA), die anatomische und physiologische Abweichungen vom linken Atrium aufweist. Verschiedene LAA-Morphologien werden unterschieden. Das LAA ist nicht nur hauptverantwortlich für intrakardiale Thromben, sondern… read more here.

recommendations! Published in 2021 at "Clinical Research in Cardiology"

DOI: 10.1007/s00392-021-01883-2

Abstract: A 71-year-old woman was admitted to our secondary care hospital because of acute heart failure and high ventricular rate atrial fibrillation (AF). The ECG showed T-wave inversion in the anterior leads and the chest X-ray… read more here.

DOI: 10.1016/j.ahj.2017.07.016

Abstract: Background The prevalence and management of left atrial appendage (LAA) thrombi associated with new anticoagulants remain to be elucidated, especially prior to atrial fibrillation (AFib) ablation. This study sought to (1) compare the prevalence of… read more here.

DOI: 10.1021/acssynbio.4c00612

Abstract: The ATP-dependent ClpXP-SspB protease complex is responsible for the degradation of intracellular proteins and is maintained at low levels in Escherichia coli to avoid nonspecific degradation. The rate-limiting step in the protease complex leads to… read more here.

DOI: 10.1053/j.semtcvs.2022.10.008

Abstract: Closure of the left atrial appendage (LAA) reduces the rates of TIA/stroke in patients in atrial fibrillation (AF) but its role in patients in sinus rhythm who undergo mitral valve repair (MV) for leaflet prolapse… read more here.

DOI: 10.1093/ehjacc/zuad036.005

Abstract: Type of funding sources: None. The most important cardiogenic reason of acute Ischemic stroke (AIS) is atrial fibrillation (AF). Left atrial (LA) enlargement (atriopathy) is one of the risk factors of atrial fibrillation. Basic bio-metric… read more here.

DOI: 10.1093/eurheartj/ehae666.032

Abstract: Left atrial (LA) and left atrial appendage (LAA) mechanical dysfunction account for an increase in cardioembolic stroke risk in atrial fibrillation (AF), and more recently in individuals in sinus rhythm (SR). However, the exact contribution… read more here.

DOI: 10.1093/eurheartj/ehae666.798

Abstract: Intracardiac echocardiography (ICE) is frequently performed during catheter ablation procedures in order to guide the transseptal puncture and has been recently used to evaluate the morphology of the LAA. The objective of this study was… read more here.

DOI: 10.1093/eurheartj/ehaf784.077

Abstract: Left atrial appendage (LAA) function plays a key role in thrombus formation. While the association between low emptying velocities and thrombi is well established, the prognostic significance of impaired LAA emptying fraction, even in the… read more here.

DOI: 10.1109/lcomm.2019.2892988

Abstract: In this letter, we propose an analytical model and conduct simulation experiments to study listen-before-talk–based unlicensed band allocation with the buffering mechanism for the License Assisted Access (LAA) packets in the heterogeneous networks. In such… read more here.
