IMPORTANCE Myocardial deformation or strain by speckle-tracking echocardiography (STE) has become an established echocardiographic modality for the diagnostic and prognostic evaluation of cardiac dysfunction. Current literature supports the incremental value of strain in diagnosis, risk stratification, and prognostication of a multitude of cardiac disease states.OBSERVATIONS Strain has been studied across the clinical spectrum from common to obscure pathologic conditions. This review presents the current literature evaluating characteristic strain patterns across this clinical spectrum, discusses prognostic implications, and provides a case series of classic strain polar maps, which are also known as bull's-eye plots.CONCLUSIONS AND RELEVANCE Characteristic bull's-eye patterns can be used to guide patient evaluation and management.

Dilated cardiomyopathy (DCM) is an important cause of the heart failure. Timely diagnosis and optimal management decrease morbidity and mortality in heart failure patients. Although transthoracic echocardiography is used as the diagnostic test of choice in these patients, new modalities like speckle tracking echocardiography (STE) have promising results in diagnosing these patients in the earlier course of the disease. Advancements in cardiac imaging are expected as more clinical studies on the role of STE in different cardiac diseases that emerge. In this review article, we will discuss the basics of STE and its role in diagnosing DCM.

“…Recent studies showed that LV deformation in the longitudinal plane estimated by speckle tracking is significantly reduced in patients with DCM, when compared with normal individuals [5]. The objective of this study was to investigate the impact of LBBB on LV deformation as measured by two-dimensional strain imaging in patients with IDCM.…”

Objectives: Left bundle branch block (LBBB) is commonly associated with heart failure. We evaluated the prevalence and impact of LBBB on left ventricular mechanics using 2D strain imaging in patients with idiopathic dilated cardiomyopathy (IDCM). Methods: We included 101 patients with IDCM with mean age 38 ± 18 years: 74% were males and 13.9% of them were in NYHA Class III-IV. LBBB was present in 26 (37%) of included patients. Myocardial mechanics including longitudinal, circumferential strain and rotation and LV synchronization were assessed using two-dimensional strain imaging. Results: LBBB group had higher LV volumes, and PAP compared with non LBBB. Peak LV longitudinal systolic strain (ε sys ) of the septum and global LV SR sys were significantly lower in LBBB compared to non LBBB group (P < 0.01, <0.03). TTP-d was greater in LBBB in comparison to non LBBB group (274.5 ± 116 versus 209.4 ± 139, P < 0.02). The electromechanical delay between septal segments was 35 ± 18 ms and between lateral wall segments: 48 ± 24 ms, between anterior wall segments: 21 ± 11 and between inferior wall segments: 41 ± 12. Consequently, LV mechanical dyssynchrony was more evident in IDCM patients with LBBB. QRS width was correlated inversely with LV longitudinal strain and strain rate and electromechanical delay (P < 0.0001) in non LBBB group. In LBBB QRS width was not related to cardiac mechanics. Using univariate analysis and after a multiple covariate adjustment, the baseline LBBB was associated with a significantly increased LV dysfunction. Conclusion: After correcting for potential confounders, LBBB was found to be associated with more deterioration of LV mechanics and exaggerated LV dyssynchrony in patients with IDCM.
