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.

Post-operative atrial fibrillation is influenced by beta-blocker therapy but not by pre-operative atrial cellular electrophysiology [PDF]

, 2006
We investigated whether post-cardiac surgery (CS) new-onset atrial fibrillation (AF) is predicted by pre-CS atrial cellular electrophysiology, and whether the antiarrhythmic effect of beta-blocker therapy may involve pre-CS pharmacological remodeling ...

Development and Validation of Machine Learning‐Based Marker for Early Detection and Prognosis Stratification of Nonalcoholic Fatty Liver Disease

Advanced Science, EarlyView.
This study constructs a stacked multimodal machine learning model for nonalcoholic fattly liver disease (NAFLD) by integrating genetic and clinical features, and synthesize an in‐silico quantitative marker (ISNLD) that enables personalized risk stratification for intrahepatic and extrahepatic outcomes of high‐risk individuals of NAFLD.

Incidence and predictors of premature ventricular complexes following catheter ablation for atrial fibrillation [PDF]

, 2017
BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia, and previous studies have focused on the epidemiology, mechanisms and risk factors for this global disease (Ryder and Benjamin 1999). Various studies have examined the mechanism,

Dual‐Energy CT‐Based Assessment of Thrombotic Heterogeneity for Predicting Stroke Source and Response to Machine Thrombectomy: A Step Toward Visualization Thrombus Treatment

Advanced Science, EarlyView.
The research indicates that dual energy CT scanning can accurately predict the stroke source and clinical outcomes by analyzing thrombus heterogeneity. Based on histopathological analysis of thrombus components, these scans are better able to display thrombus details than standard CT scans, which is helpful for the development of visual navigation ...

Anatomy of the shape of the cavity and the internal relief of the walls of the left atrial appendage

Учёные записки Санкт-Петербургского государственного медицинского университета им. Акад. И.П. Павлова, 2022
Introduction. The evaluation of the shape of the left atrial appendage into interconnection with the internal relief of its wall is of an importance for discovering anatomical patterns of the left atrium, which appears to be the most thrombogenic and are

A heterozygous variant in the human cardiac miR-133 gene, MIR133A2, alters miRNA duplex processing and strand abundance [PDF]

, 2016
BACKGROUND MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression. Sequential cleavage of miRNA precursors results in a ~22 nucleotide duplex of which one strand, the mature miRNA, is typically loaded into the ...
