Noninvasive Myocardial Strain Measurement by Speckle Tracking Echocardiography

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

Intraindividual comparison of circumferential strain using speckle tracking by echocardiography versus CMR feature tracking and myocardial tagging in patients

Background Left ventricular myocardial motion analysis and the assessment of regional dysfunction are crucial for the detection and prognosis in different cardiac pathologies. Myocardial tagging (MT) is a cardiac magnetic resonance (CMR) based method for tracking myocardial motion, which has been established as reference standard for assessment of strain. Currently, strain can also be assessed ...

Normal range of myocardial layer-specific strain using two-dimensional speckle tracking echocardiography

BACKGROUND Newer 2D strain software has a potential to assess layer-specific strain. However, normal reference values for layer-specific strain have not been established. We aimed to establish the normal ranges of layer-specific longitudinal and circumferential strain (endocardial global longitudinal strain (GLS), transmural GLS, epicardial GLS, endocardial global circumferential strain (GCS), ...

Cardiac Mechanics Evaluated by Speckle Tracking Echocardiography

Natural myocardial markers, or speckles, originated from constructive and destructive interference of ultrasound in the tissues may provide early diagnosis of myocardial changes and be used in the prediction of some cardiac events. Due to its relatively temporal stability, speckles can be tracked by dedicated software along the cardiac cycle, enabling the analysis of the systolic and diastolic ...

Assessment of Subclinical Myocardial Changes in Non-Alcoholic Fatty Liver Disease: A Case-Control Study Using Speckle Tracking Echocardiography

Background: Considering the association between cardiac abnormalities and non-alcoholic fatty liver disease (NAFLD), the present study aimed to evaluate the relationship between biopsy-proven NAFLD and functional echocardiographic parameters, including left ventricular (LV) global longitudinal strain (GLS) in asymptomatic individuals. Methods: Thirty asymptomatic patients with liver biopsy-prov...
