491 LA volumes, global left atrial strain and strain rate in normal hearts determined by 2-D echocardiography

Do left atrial strain and strain rate reflect intrinsic atrial function, or are they determined by left ventricular function?

BACKGROUND Left atrial (LA) strain (S) and strain rate (SR) are reported as measures of intrinsic function. AIM Since the LA and left ventricle (LV) are connected through the mitral annulus, we investigated: (1) if deformation indices in the LA are mostly predicted by deformation of the LV; (2) if timings of S and SR events are similar in both the LA and LV; and (3) if alteration of S and SR ...

Assessment of left ventricular function by strain-strain rate echocardiography in patients with celiac disease.

BACKGROUND/AIM Celiac is predominantly a disease of the small intestine characterized by chronic malabsorption in genetically susceptible individuals who ingest grains containing. gluten, such as wheat, barley, and rye. In the present study, we evaluate left ventricular function in patients with celiac disease by using strain and strain rate echocardiography imaging. MATERIALS AND METHODS Twe...

Left Atrial Mechanical Function and Global Strain in Hypertrophic Cardiomyopathy

BACKGROUND Atrial fibrillation is the most common arrhythmia and is associated with adverse outcomes in hypertrophic cardiomyopathy (HCM). Although left atrial (LA) remodeling and dysfunction are known to associate with the development of atrial fibrillation in HCM, the changes of the LA in HCM patients remain unclear. This study aimed to evaluate the changes in LA size and mechanical function ...
