Incremental value of left atrial mechanical dispersion over CHA DS -VASc score in predicting risk of thrombus formation.

Purpose: To assess the potential ability of two-dimensional speckle tracking analysis (STE) during atrial fibrillation (AF) to identify patients with LA appendage thrombi (LAAT).

Methods: This study involved 93 patients with AF (39% female, 67.1 ± 9.

The impact of the latest echocardiographic chamber quantification recommendations on the prediction of left atrial appendage thrombus presence by transthoracic echocardiography.

Introduction: The latest recommendations for echocardiographic chamber quantification have implemented updated normal values for all cardiac chambers.

Purpose: To evaluate the incidence of normal and abnormal values of routine echocardiographic parameters such as left ventricular ejection fraction (LVEF) and left atrial volume indexed to body surface area (LAVi) in patients with non-valvular atrial fibrillation (AF) and to determine the influence of LVEF and LAVi reclassification on the prediction of LAAT by transthoracic echocardiography.

Methods: We retrospectively analysed the database of 1674 transesophageal echocardiograms performed between 2012 and 2015 in our echo lab.

Association between left atrial function assessed by speckle-tracking echocardiography and the presence of left atrial appendage thrombus in patients with atrial fibrillation.

Objective: The aim of the study was to investigate whether the deformation of left atrium (LA) measured by speckle-tracking analysis (STE) is associated with the presence of LA appendage thrombus (LAAT) during non-valvular atrial fibrillation (AF).

Methods: Eighty-seven patients (mean age 67 years, 59% men) were included to retrospective cross-sectional study. On top of standard echocardiography we assessed: LA longitudinal systolic strain (LS), systolic (LSSR) and early diastolic strain rate (LESR) in four-chamber and twochamber apical views.

Left Atrial Dysfunction Assessed by Two-Dimensional Speckle Tracking Echocardiography in Patients with Impaired Left Ventricular Ejection Fraction and Sleep-Disordered Breathing.

Aims: To evaluate the relationship between left atrial (LA) structure and deformation obtained by two-dimensional speckle tracking echocardiography (2DSTE): peak longitudinal systolic strain (LAs), peak longitudinal systolic strain rate (LAS-SR), peak longitudinal early diastolic strain rate (LAE-SR), peak longitudinal late diastolic strain rate (LAA-SR), and sleep-disordered breathing (SDB) estimated by means of apnea-hypopnea index (eAHI).

Methods: Thirty-two individuals with ischemic heart disease (IHD) and impaired left ventricular ejection fraction (EF < 50%) were included in the study. LA function was assessed using 2DSTE.
