Clinical Implementation

This work reviews the reasons why the characteristics of left ventricular (LV) contractility, in particular, and 2D speckle echocardiography-based peak rates of global longitudinal strain (GLS), are not widely used in clinical practice. Authors present the analysis of new indicators proposed for the assessment ofLVcontractile function based on longitudinal strain taking into account the involvement of individual segments. The authors show that the assessment of myocardial work indicators characterizing the relationships between contractile and pump functions is a promising approach for the study ofLVcontractile function. The analysis of postsystolic strain index (PSI) is presented to illustrate its clinical implementation in the studies of viable myocardium in ischemic conditions and evaluating the effectiveness of cardiac resynchronization therapy (CRT).

Two-dimensional speckle-tracking echocardiography (2D–STE) is an advanced echocardiographic technique based on deformation imaging that allows comprehensive evaluation of the myocardial function. Clinical application of 2D–STE holds great potential for its ability to provide valuable information on both global and regional myocardial function and to quantify cardiac rotation and synchronicity, which are not readily possible with the conventional echocardiography. It has gained growing importance over the past decade, especially in human medicine, and its application includes assessment of myocardial function, detection of subclinical myocardial dysfunction and serving as a prognostic indicator. This review illustrates the fundamental concepts of deformation analysis and gives an overview of the current understanding and its clinical application of this technique in veterinary medicine, with a focus on early detection of left ventricular (LV) dysfunction in dogs.
