Reliability of echocardiographic speckle-tracking derived bi-atrial strain assessment under different hemodynamic conditions

myocardial strain and strain rate imaging: comparison between doppler derived strain imaging and speckle tracking echocardiography

Feasibility, Reproducibility, and Agreement between Different Speckle Tracking Echocardiographic Techniques for the Assessment of Longitudinal Deformation

BACKGROUND Left ventricular (LV) longitudinal deformation can be assessed with new echocardiographic techniques like triplane echocardiography (3PE) and four-dimensional echocardiography (4DE). We aimed to assess the feasibility, reproducibility, and agreement between these different speckle-tracking techniques for the assessment of longitudinal deformation. METHODS 101 consecutive subjects u...

Abnormal atrial strain with speckle-tracking echocardiography predicts the arrhythmic substrate of atypical right atrial flutter

This is an op under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4 Introduction Atypical atrial flutter is defined as macroreentrant atrial tachycardia (AT) that does not involve the cavotricuspid isthmus; a variety of reentrant circuits may include reentry around the mitral valve annulus or scar tissue w...

Can speckle-tracking imaging improve the reliability of echocardiographic parameters for outcome evaluation in clinical trials?

Echocardiography has been used for the assessment of left ventricular (LV) structureand function over almost threedecades, and it is the de facto clinical standard for two-dimensional (2D) quantification of LV dimensions, and systolic and diastolic function. In agreement with this, echocardiography is also a commonly used imaging modality in the management of patients with acute myocardial infa...

Impact of Gout on Left Atrial Function: A Prospective Speckle-Tracking Echocardiographic Study

The purpose of our study was to evaluate the left ventricular (LV) and left atrial (LA) function in patients with gout. A total of 173 patients underwent a comprehensive Doppler-echocardiography examination. Participants were divided into four groups-Stage 0: control (n = 35), Stage I: asymptomatic hyperuricemia (n = 30), Stage II: gouty arthritis without tophi (n = 58), and Stage III: tophaceo...
