Strain Echocardiography to Predict Postoperative Atrial Fibrillation [PDF]

International Journal of Molecular Sciences, 2022
Postoperative atrial fibrillation (POAF) complicates 15% to 40% of cardiovascular surgeries. Its incidence progressively increases with aging, reaching 50% in octogenarians. This arrhythmia is usually transient but it increases the risk of embolic stroke, prolonged hospital stay, and cardiovascular mortality.

Relationship Between Atrial Dysfunction and Atrial Arrhythmias in Adults With Fontan Palliation: Role of Atrial Strain Imaging

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Atrial dysfunction is a risk factor for atrial arrhythmia and can be detected by atrial strain imaging in patients with biventricular circulation.

The Learning Curve for Left Atrial Strain Analysis

Journal of the American Society of Echocardiography
Left atrial (LA) strain, in particular, LA reservoir stxrain, has emerged as an important quantitative tool for the assessment of LA function in patients with heart failure, atrial fibrillation, valvular heart disease, and noninvasive estimation of left ventricular (LV) filling pressures.1 However, LA deformation analysis by two-dimensional speckle ...

Linking Epicardial Adipose Tissue to Atrial Remodeling: Clinical Implications of Strain Imaging

Hearts
Atrial fibrillation is a prevalent cardiac arrhythmia influenced by multifactorial mechanisms, including the emerging role of epicardial adipose tissue. Left atrial epicardial adipose tissue, through its endocrine and paracrine activities, contributes to

Left atrial sphericity in relation to atrial strain and strain rate in atrial fibrillation patients

The International Journal of Cardiovascular Imaging, 2023
Abstract Purpose Left atrial (LA) sphericity is a novel, geometry-based parameter that has been used to visualize and quantify LA geometrical remodeling in patients with atrial fibrillation (AF). This study examined the association between LA sphericity, and LA longitudinal strain and strain rate measured by feature ...

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

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 ...

Systematic Analysis of Gene Expression Differences between Left and Right Atria in Different Mouse Strains and in Human Atrial Tissue [PDF]

, 2011
Background: Normal development of the atria requires left-right differentiation during embryonic development. Reduced expression of Pitx2c (paired-like homeodomain transcription factor 2, isoform c), a key regulator of left-right asymmetry, has recently ...
