The Review explains the fundamental concepts of deformation imaging, describes in a comparative manner the two major deformation imaging methods Ecohkardiographie and speckle tracking 2D-strain derived and discusses the clinical applicability of these new echocardiographic tools, which recently have become a subject of great interest for clinicians. Echokxrdiographie work performed on adult dogs showed that global diastolic strain rate can be useful for the assessment of ventricular relaxation and estimation of filling pressures [ 28 ].

An example of myocardial strain changes during acute rejection is shown in Fig. Ventricular wall motion basucs and displacement is position dependent. Thus, during systole, in addition to radial wall thickening and longitudinal wall shortening, the left ventricle LV also rotates about its long axis and translates anteriorly. Please review our privacy policy.

The spectrum of potential clinical applications is very wide due its ability to differentiate between active and passive movement of myocardial segments, to quantify intra-ventricular dyssynchrony and to evaluate components of myocardial function such as longitudinal myocardial shortening that are not visually assessable.

Strain and Strain Rate Imaging by Echocardiography – Basic Concepts and Clinical Applicability

The high sensitivity of both TDI-derived and 2D speckle tracking derived strain and strain echokardoographie data for the early detection of myocardial dysfunction recommend this new non-invasive diagnostic method for routine clinical use. Non-Doppler two-dimensional strain imaging by echocardiography — from technical considerations to clinical applications.


An ultrasound speckle tracking cehokardiographie strain analysis of myocardial deformation in profesional soccer players compared with healthy subjects and hypertrophic cardiomyopathy. Speckle tracking echocardiography is a sensitive tool for detection of myocardial ischemia: One month later global strain values were several times higher and regional strain curves indicated uniform circumferential shortening and radial thickening C and Drespectively.

Myocardial strain by Doppler echocardiography. Contact Credits Site map. The clinical usefulness of echocardiographic strain and SR imaging in children is another important aspect, especially because in these patients the impact of heart rate HR on strain and SR measurements is more evident than in adults. Impact of left ventricular lead position in cardiac resynchronization therapy on left ventricular remodeling.

Arch Mal Coeur Vaiss. Measurement of regional myocardial electro-mechanical events with velocity data acquired with tissue Doppler imaging facilitate identification of mechanical dyssynchrony and has been shown to be useful to select patients who may better respond to CRT [ 88 ].

Impact of myocardial structure and function postinfarction on diastolic strain measurements: Speckle-tracking stain echocardiography for detecting cardiac dyssynchrony in a canine model of dyssynchrony and heart failure. Thus for a one-dimensional 1D object i.

A two-dimensional speckle strain study. The intraobserver and interobserver variability for 2D-strain and SR measurements were found to be low: Detection of subclinical cardiac involvement in systemic sclerosis by Echocardiographic stain imaging. Strain imaging, echocardiography, myocardial contraction, diagnosis, prognosis. Combined longitudinal and radial dyssynchrony predicts ventricular response after resynchronization therapy.

The effect of cardiac resynchronization on morbidity and mortality in heart failure. Speckle Tracking Echocardiography Myocardial velocity gradients detected by Doppler imaging. Our research-based and practice-proven teaching strategies help you to echokardioographie your goals.


Global diastolic strain rate for assessment of left ventricular relaxation and filling pressure. The lack of angle dependency is a great advantage of non-Doppler 2D-strain imaging in comparison to TDI-derived strain data. Due to its ability to differentiate between active and passive movement of myocardial segments, to quantify intraventricular dyssynchrony and to evaluate components of myocardial function, such as longitudinal myocardial shortening, that are not visually assessable, it allows comprehensive assessment of myocardial function and the spectrum of potential clinical applications is very wide.

At the same time, as revealed by 2D strain imaging, longitudinal shortening, which is usually not visible with the naked eye, was not affected Fig. Validation of echokarduographie new method to quantify regional myocardial function.

Early detection of left ventricular dysfunction related to transplant coronary artery disease. Introduction We have created this online interactive module to assist with teaching and learning the assessment of cardiac function with transthoracic echocardiography.

Strain and Strain Rate Imaging by Echocardiography – Basic Concepts and Clinical Applicability

N Engl J Med. A head to head comparison between 2D-strain and tissue Doppler derived strain analysis. Strain and strain rate data also provide valuable prognostic information, especially for prediction of future reverse remodelling after left ventricular restoration surgery or after CRT and prediction of short and median-term outcome without transplantation or ventricular assist device implantation of patients referred for HTx.
