Displacement of occluder after left atrial appendage closure: A case report

open access: yesClinical Case Reports
Key Clinical Message Atrial fibrillation is closely associated with thrombotic events. In non‐valvular atrial fibrillation, 90% of thrombi are formed by the left atrial appendage.

Chronic beta-adrenoceptor blockade and human atrial cell electrophysiology: evidence of pharmacological remodelling [PDF]

open access: yes, 2003
<b>Objective:</b> Chronic beta-adrenoceptor antagonist (β-blocker) treatment reduces the incidence of reversion to AF in patients, possibly via an adaptive myocardial response.

Conformable Microelectrode Arrays Integrated with a Scoop‐Shaped Slide‐Well for Dynamic Electrophysiological Profiling of Patient‐Derived Cardiac Organoids

open access: yesAdvanced Science, EarlyView.
A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.

The effect of the pericardial patching exclusion technique for left atrial appendage closure on postoperative reopening rate

open access: yesBMC Cardiovascular Disorders
Background The left atrial appendage (LAA) is the primary source of cardiogenic embolism in atrial fibrillation patients. Traditional LAA closure methods have shown suboptimal clinical outcomes.

Catheter ablation of atrial fibrillation : radiofrequency catheter ablation for redo procedures after cryoablation [PDF]

open access: yes, 2013
Aim: To evaluate the effectiveness of two different strategies using radiofrequency catheter ablation for redo procedures after cryoablation of atrial fibrillation. Methods: Thirty patients (paroxysmal atrial fibrillation: 22 patients, persistent atrial

Organ‐Specific and Conserved Regulatory Logic Orchestrates Gene Expression in the Embryonic Mesothelium

open access: yesAdvanced Science, EarlyView.
Integrated multi‐omic profiling maps the gene‐regulatory landscape of the coelomic mesothelium across heart, lung, and pancreas. A cardiac‐restricted regulatory program is uncovered in which TBX20 activates heart mesothelial (epicardial) cis‐regulatory elements, while MAF emerges as a conserved regulator of mesothelial identity.

Giant left atrial appendage aneurysm [PDF]

open access: yesEuropean Heart Journal - Cardiovascular Imaging, 2014
A 35-year-old black man without cardiovascular risk factor presented with dizziness. Physical examination found an irregular cardiac rhythm and ECG revealed atrial fibrillation with a slow ventricular response. Brain magnetic resonance imaging (MRI) showed small and recent vertebrobasilar ischaemic strokes.

G3BP1 Succinylation at K413 is Critical for Cardiac Function by Modulating PI3K‐AKT‐mTOR Signal Axis

open access: yesAdvanced Science, EarlyView.
Schematic illustrating the impact of G3BP1 succinylation at K413 on cardiac function. In the healthy human heart, G3BP1 succinylation maintains homeostatic mTOR signaling. In patients with dilated cardiomyopathy (DCM) and heart failure (HF), G3BP1 de‐succinylation induces RagA expression and disrupts the binding of the TSC1/2 complex, leading to the ...

Left Atrial Appendage Occlusion Guided Only by Transesophageal Echocardiography

open access: yesCardiology Research and Practice, 2019
Aims. To investigate a new method of left atrial appendage occlusion without fluoroscopy. Methods and Results. We performed left atrial appendage occlusion for 14 patients with atrial fibrillation in our hospital. All of the surgeries were completed in a
