Therapeutic Dilemma of Natural Watchman: Congenital Absence of the Left Atrial Appendage

open access: yesCase Reports in Cardiology, 2018
Congenital absence of the left atrial appendage is a rare congenital cardiac anomaly which is usually an incidental finding. We present a rare case of congenital absence of the left atrial appendage in a 77-year-old female patient with atrial ...

Bilateral atrial appendage aneurysms associated with atrial fibrillation. [PDF]

open access: yes, 2014
Aneurysm of the left atrial appendage is an extremely rare anomaly. We describe the case of a 68-year-old man who presented with palpitation and was found to have a very large aneurysm located near the left atrial appendage on routine echocardiography ...

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 ...

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.

History of Percutaneous Left Atrial Appendage Occlusion with AMPLATZER Devices.

open access: yes, 2018
AMPLATZER devices preceded WATCHMAN occluder in 2002 for catheter-based left atrial appendage occlusion. The AMPLATZER technique facilitates simultaneous closure of atrial shunts using two devices through one gear.

Redefining Crystalline Silicon: Unlocking New Horizons in Transparent and Flexible Photovoltaics

open access: yesAdvanced Energy Materials, EarlyView.
Crystalline silicon is presented as a platform for transparent and flexible photovoltaics. This review article outlines design principles for optical strategies to fabricate transparent silicon solar cells, mechanical strategies that mitigate silicon brittleness, and emerging concepts such as singlet‐fission spectral conversion and tandem architectures,

Shapley Additive Explanation for Local Class Differentiation: Local Explainability for Class Differentiation in Classification Models

open access: yesAdvanced Intelligent Systems, EarlyView.
An instance‐level, model‐agnostic explanation of class differentiation is introduced through SHAP‐LCD, linking probability shifts to feature‐wise Shapley contributions. The method operates on tabular and image data and is released in a fully reproducible implementation, offering a transparent way to examine, at each instance, why predictive models ...
