“…The strength of strain imaging is in its robust reproducibility when using vendor-specifi c analy c algorithms. 79 With sequenal strain analysis, changes in myocardial GLS and GCS seem to precede threshold changes in LVEF used to defi ne cardiotoxicity. The American Society of Echocardiography and European Associa on of Cardiovascular Imaging (ASE/EACVI) posi on statement has suggested using a rela ve reduc on in GLS by more than 15% to defi ne subclinical cardiotoxicity (i.e., without a substan al reduc on in LVEF).…”

Cancer therapies can cause a variety of cardiac toxicities, including ischemia, cardiomyopathy, heart failure, myocarditis, arrhythmias, vascular disease, hypertension, and hyperlipidemia. Addressing cardiovascular risk at baseline, before initiating therapy, during cancer treatment, and in the survivorship period is imperative. It may be useful to risk stratify individuals with cardiovascular risk factors using biomarkers or imaging before they receive potentially cardiotoxic therapies. Additionally, new guidelines recommend cardiac imaging with echocardiography in the survivorship period 6 to 12 months after completing cancer therapy for these high-risk individuals. Close collaboration between cardiology and oncology in both clinical practice and future research is essential.

“…Carefully designed studies also assessed specific aspects of reproducibility when measuring peak global and regional strain from commercial software (Barbier et al 2015;Cheng et al 2013;Mirea et al 2018a;Oxborough et al 2012;Shiino et al 2017). In an educational perspective, the influence of the training level of the operators was also examined (Chan et al 2017;Negishi et al 2017;Yamada et al 2014). In our study, the questionnaire about the participants' background and experience with speckle-tracking was anonymous, which precluded from investigating the quality of each operator's measurements against his/her experience.…”

Variability in global and regional peak strain has been thoroughly studied, but not the variability in the spatiotemporal myocardial strain patterns. This study reports on such variability and its implications for adequate disease interpretation. Forty in-training operators were distributed on 20 workstations, and analyzed six cases with representative deformation patterns with commercial speckle-tracking. Inter-operator differences were quantified through the variability in myocardial delineations, spatiotemporal longitudinal strain patterns, and peak longitudinal strain. Intra-operator differences were assessed similarly using 10 repeated measurements from a single clinician expert. Delineations varied mainly along the lateral wall and at the valve level. Peak longitudinal strain variability was low to moderate. The spatiotemporal strain patterns were consistent despite high variability at the apex and near the valve. The results indicate that relevant pattern assessment is possible despite heterogeneous experience with speckle-tracking, and that careful interpretation of pattern abnormalities should be recommended before a more systematic quantitative analysis.

“…It is essential to stress the fact that the concordance in LV-GLS values is greatly affected by operators' experience, but despite that it has been proved that the measurement of LVEF is far more variable than the assessment of LV-GLS, regardless the quality of echo images. 8 Longitudinal strain is capable of an accurate and early detection of the alterations that may affect the subendocardial longitudinal fibers, 9 such as an ischemic injury. 10 The same fibers are also involved since the very first stages of other diseases, like arterial hypertension (AH), and LS can be extremely useful in a subclinical phase when LVEF is typically normal.…”

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

Speckle tracking echocardiography (STE) cannot be considered a recent technique anymore. Its application has gained growing importance over the last decade in several clinical settings, and the deformation analysis has fully entered in diagnostic algorithms and guidelines of various pathologies. STE allows to track the displacement of "speckles" in two-dimensional (2D) echocardiographic images in an angleindependent way and to assess their movement (strain) during the cardiac cycle. Its high feasibility, reproducibility, and accuracy have been widely demonstrated. In this review, we describe how STE has been applied to different aspects of the daily clinical practice, including ischemic heart diseases, heart valve disease, heart failure, and prognostication, highlighting the possible added value that strain parameters have shown over the years.
