The Influence of Angle of Insonation and Target Depth on Speckle-Tracking Strain

Immediate mechanical effects of acute left bundle branch block by speckle tracked strain

“…It should be noted that evaluation of longitudinal strain for the classic pattern involves only the basilar and mid left ventricular segments. Continued experience with longitudinal strains from the apical segments is highly variable and may be due to a variety of reasons as discussed by Forsha [18].…”

“…Additionally, Forsha et al 9 showed that strain values are modestly dependent on angel of insonation and target depth in a pediatric population. Additionally, Forsha et al 9 showed that strain values are modestly dependent on angel of insonation and target depth in a pediatric population.…”

More than 10 years of speckle tracking echocardiography: Still a novel technique or a definite tool for clinical practice?

“…80 For these reasons, strain parameters should not be analyzed in subcostal images, off-axis apical imaging, or patients in which an optimal window cannot be defined. 81 In order to avoid these difficulties as much as possible, STE requires expert technical knowledge and the operator's training might constitute a cost that not always can be reimbursed, even though it has been proven to be a technique that is quickly learned compared to other advanced echocardiographic techniques. In addition to these technical difficulties, STE necessitates an offline analysis that undoubtedly prolongs examination time and that is not always possible, especially in critical settings.…”
