Impact of the MitraClip Procedure on Left Atrial Strain and Strain Rate [PDF]

Circulation: Cardiovascular Imaging, 2018
Background— Although reverse remodeling of the left atrium (LA) has been shown after MitraClip placement in degenerative mitral regurgitation (MR), changes in LA strain and strain rate have not been evaluated in these patients or compared with surgical mitral valve repair. Methods and Results—

Exploring Hidden Left Ventricular Dysfunction in COPD Patients without Pulmonary Hypertension [PDF]

Al-Azhar International Medical Journal
Background: Atrial fibrillation (AF) is associated with left atrial (LA) mechanical dysfunction and an increased risk of thromboembolism, most commonly originating from the left atrial appendage (LAA).

Role of 2D speckle-tracking echocardiography in the assessment of left atrial function and its relation to the presence of left atrial appendage thrombus in patients with non-valvular paroxysmal atrial fibrillation

Al-Azhar Assiut Medical Journal, 2020
Introduction The study aimed to evaluate the role of speckle-tracking echocardiography (STE) in the assessment of left atrial (LA) function and its relation to the presence of left atrial appendage thrombus (LAAT) compared with the gold standard ...

Association Between the Left Atrial and Left Atrial Appendages Systole Strain Rate in Patients with Atrial Fibrillation [PDF]

Medical Science Monitor, 2016
BACKGROUND The aim of this research was to explore the association between the left atrial (LA) and left atrial appendages (LAA) systole strain rate (SSR) in patients with atrial fibrillation (AF), and to provide evidence to aid in the assessment of disease progression.

Structure-based finite strain modelling of the human left ventricle in diastole [PDF]

, 2013
Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

Cardiac mechanics and incident ischemic stroke: the Cardiovascular Health Study

Scientific Reports, 2021
Recent evidence indicates that our understanding of the relationship between cardiac function and ischemic stroke remains incomplete. The Cardiovascular Health Study enrolled community-dwelling adults ≥ 65 years old. We included participants with speckle-
