Different Techniques of Surgical Left Atrial Appendage Closure and Their Efficacy: A Systematic Review

Reviews in Cardiovascular Medicine, 2023
Background: Atrial fibrillation has been identified as an independent risk factor for thromboembolic events. Since 1948 different surgical techniques have described the feasibility and the rationale of left atrial surgical appendage closure.

Limited Ability to Activate Protein C Confers Left Atrial Endocardium A Thrombogenic Phenotype: A Role in Cardioembolic Stroke? [PDF]

, 2011
Background and Purpose—Atrial fibrillation is the most important risk factor for cardioembolic stroke. Thrombi form in the left atrial appendage rather than in the right. The causes of this different thrombogenicity are not well-understood.

A Misleading Left Atrial Appendage

JACC: Case Reports, 2023
Left atrial appendage collapse is a relatively unusual echocardiographic finding. Although in post-cardiac surgery patients it may be an early sign of cardiac tamponade, and pericardiocentesis should be discussed, a conservative approach may be followed in cases secondary to viral infection without confusing it with a left atrial appendage thrombus ...

Discovering Interpretable Semantics from Radio Signals for Contactless Cardiac Monitoring

Advanced Science, EarlyView.
This study presents a semantic representation framework for clinically interpretable cardiac monitoring from contactless radio signals. It formulates radio semantic learning as an information‐bottleneck problem and approximates the objective via intra‐modal compression and cross‐modal alignment, structuring radio measurements into meaningful semantic ...

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

Advanced 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 ...

Efficacy and Safety of Catheter Ablation Combined with Left Atrial Appendage Closure in the Treatment of Atrial Fibrillation: A Systematic Review and Meta-Analysis

Anatolian Journal of Cardiology, 2022
Background: Catheter ablation combined with left atrial appendage closure is effective in treating atrial fibrillation. However, the effectiveness of this combined treatment compared with catheter ablation alone is still controversial.

LEFT ATRIAL APPENDAGE SEAL FOLLOWING PERCUTANEOUS LEFT ATRIAL APPENDAGE OCCLUSION

Journal of the American College of Cardiology, 2020
Percutaneous left atrial appendage (LAA) occlusion is well established as an alternative to anticoagulation therapy for stroke prophylaxis among patients with non-valvular atrial fibrillation (NVAF). Only the Watchman® device has FDA approval for this indication.

The missing left atrial appendage [PDF]

Journal of Cardiovascular Computed Tomography, 2012
A 34 year old man underwent a transesophageal echocardiogram (TEE) prior to implantation of a biventricular ICD and DC cardioversion, to exclude left atrium and left atrial appendage thrombus. He had a history of repaired tetralogy of Fallot as a child, Stickler syndrome, atrial flutter and was status post recent mitral valve replacement, pulmonary ...
