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.

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.
