Standardized myocardial segmentation for echocardiography and cardiac imaging Cardiovascular imaging modalities have developed rapidly in the past few decades. The repertoire of available methods includes…
Myocardial deformation: strain, strain rate, speckle tracking As previously discussed, the left ventricular wall can be subdivided into three layers: the inner lining (endocardium), a…
Fractional shortening (FS) for estimating systolic function Fractional shortening (FS) is calculated by measuring the percentage change in left ventricular diameter during systole. It is…
Ventricular ejection fraction (EF) For several decades, ejection fraction (EF) has been the dominating method for assessing left ventricular systolic function. Ejection fraction is simple…
Size and mass of the left ventricle Left ventricular mass is a flawed proxy for ventricular systolic function and load. The mass is, however, an…
Methods for assessing systolic function (contractile function) Several echocardiographic measurements are available to assess left ventricular systolic function. These methods elucidate slightly different aspects of…
Ventricular Pressure-Volume Relationship Left ventricular pressure-volume relationship can be described by a loop diagram with volume depicted on the x-axis and left ventricular pressure on…
Structure and contractile function of myocardial fibers The left ventricular wall can be subdivided into several layers. These layers are similar to those seen in…
Left ventricular function and its echocardiographic assessment Cardiac function depends on a large number of parameters, including atrial function, valvular function, and ventricular function. A…
The standard transthoracic echocardiographic examination This chapter presents a sequential series of images that comprise a complete standard echocardiographic examination. The image views are discussed…
