Strain Rate Imaging for Assessment of Regional Myocardial Function

Quantification of Regional Myocardial Function following Acute Myocardial Infarction by Ultrasonic Strain Rate and Strain Imaging

Objectives: The rapid diagnosis and early risk stratification of patients presenting with acute myocardial infarction (AMI) is important. In experimental setting ultrasonic strain rate (SR) and strain (S) have been shown to identify changes in deformation predictive of ischemia. We sought to evaluate and compare regional myocardial function at “the risk zone” (ARZ) supplied by the culprit coron...

Strain rate imaging for assessment of regional myocardial function: results from a clinical model of septal ablation.

BACKGROUND Regional myocardial function assessment is essential in the management of coronary artery disease (CAD). Tissue Doppler imaging (TDI) by depicting local myocardial motion can potentially quantify regional myocardial function. Strain rate imaging (SRI) that depicts regional deformation is less susceptible to cardiac translation and tethering and may be superior to TDI for regional fun...

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

Early impairment of myocardial function in systemic sclerosis: non-invasive assessment by Doppler myocardial and strain rate imaging.

BACKGROUND Aim of the present study was to analyze both left (LV) and right ventricular (RV) myocardial function in patients with Systemic Sclerosis (SSc), and their relation to other instrumental features of the disease. METHODS AND RESULTS Twenty-five healthy subjects and 23 age- and sex-comparable asymptomatic patients classified as having either diffuse (11 patients) or limited form (12 p...

Quantitative assessment of intrinsic regional myocardial deformation by Doppler strain rate echocardiography in humans.

Myocardial Deformation by Doppler Strain Rate Echocardiography in Humans To the Editor: We have read with interest the recent report of Edvardsen et al1 in which left ventricular regional peak systolic strain values measured by ultrasound were correlated with the corresponding strain data extracted by 3-dimensional tagged MRI. The study showed an overall acceptable agreement between the 2 techn...
