Left atrial strain: a new predictor of thrombotic risk and successful electrical cardioversion

Echo Research and Practice, 2016
Background: Left atrial deformation (LAD) parameters are new markers of atrial structural remodelling that seem to be affected in atrial fibrillation (AF) and atrial flutter (AFL).

Left Ventricular Strain and Left Atrial Strain Are Impaired During Hemodialysis in Children [PDF]

The International Journal of Cardiovascular Imaging, 2021
Abstract Purpose We aimed to investigate intradialytic changes in ventricular and atrial function using speckle tracking echocardiography (STE) in pediatric hemodialysis (HD). Methods Children with HD vintage > 3 months were enrolled, and echocardiography was performed prior to, during, and after HD. STE was analyzed using GE EchoPAC. Left

Left Atrial Strain: Crucial Cardiac Navigator in Practice

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2023
Left ventricular (LV) diastolic pressure estimation is essential for characterization of heart failure. Despite extensive research and the availability of numerous metrics, the assessment of LV diastolic pressures both at rest and after exertion has been

Evaluation of the relationship between left atrial strain and exercise tolerance in patients with hypertrophic cardiomyopathy by treadmill stress echocardiography

Frontiers in Cardiovascular Medicine, 2023
ObjectiveThe aim of this study is to evaluate the left atrial strain (LAS) in patients with hypertrophic cardiomyopathy (HCM) by treadmill exercise stress echocardiography, combined with three-dimensional speckle tracking technology, for predicting ...

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 ...

Left Atrial Strain [PDF]

Circulation: Cardiovascular Imaging, 2017
Left atrial (LA) function has been the subject of study for many years.1 Interesting pathophysiological concepts have been described but to date, not many of these results have been translated into real clinical use and value.2 Doppler and volumetric approaches were the first methods used to assess LA function.

Pre- and postoperative left atrial and ventricular volumetric and deformation analyses in severe aortic regurgitation

Cardiovascular Ultrasound, 2021
Background The impact of volume overload due to aortic regurgitation (AR) on systolic and diastolic left ventricular (LV) indices and left atrial remodeling is unclear.

Impaired left atrial reservoir and conduit strain in patients with atrial fibrillation and extensive left atrial fibrosis [PDF]

Journal of Cardiovascular Magnetic Resonance, 2021
Atrial fibrillation (AF) is associated with profound structural and functional changes in the atria. In the present study, we investigated the association between left atrial (LA) phasic function and the extent of LA fibrosis using advanced cardiovascular magnetic resonance (CMR) imaging techniques, including 3-dimensional (3D) late gadolinium ...

The Effect of TAVR on Left Ventricular and Left Atrial Mechanics in Patients with Aortic Stenosis

Journal of Cardiovascular Development and Disease, 2022
Background. Measures of adverse cardiac remodeling, left ventricular global longitudinal strain (LVGLS) and left atrial (LA) phasic function, are predictive of cardiac events in patients with severe aortic stenosis (AS).
