Background  Myocardial deformation integrated with cardiac dimensions provides a comprehensive assessment of the ventricular remodelling patterns induced by cumulative effects of intensive exercise. Feature tracking(FT) can measure myocardial deformation from cardiac magnetic resonance(CMR) cine sequences; however, its accuracy is still scarcely validated. Purpose  Our aim was to compare FT’s accuracy and reproducibility to speckle tracking echocardiography (STE) in highly trained endurance athletes (EAs). Methods  93 EAs (>12 hours training/week during the last 5 years, 52% male, 35 ± 5.1 years) and 72 age-matched controls underwent a resting CMR and a transthoracic echocardiography to assess biventricular exercise-induced remodelling and biventricular global longitudinal strain (GLS) by CMR-FT and STE. Results   High endurance training load was associated with larger bi-ventricular and bi-atrial sizes and mildly reduced systolic function of both ventricles (p < 0,05). Strain values (both by CMR-FT and STE) proportionally decreased with increasing ventricular volumes potentially depicting the increased volume and functional biventricular reserve that characterize EAs heart. Strain values were lower when assessed by CMR-FT as compared to STE (p < 0.001), with good reproducibility for the LV (bias = 3.94%, LOA= ± 4.27%) but wider variability for RV strains (Figure 2). Conclusions   Biventricular longitudinal strain values were lower when assessed by FT compared to STE. Both methods were comparable when measuring LV strain but not RV strain. These differences might be justified by FT’s lower in-plane spatial and temporal resolution, which is particularly relevant for the complex anatomy of the RV. Abstract Figure. Fig 1.

Aims The aim of the study was to evaluate left ventricular (LV) remodeling and systolic function using two-dimensional speckle tracking echocardiographic (2D STE) imaging in children at a long-term (more than 36 months, 107.5±57.8 months) after balloon valvuloplasty for aortic stenosis (BAV). Methods and results 40 patients (mean age 9,68 years, 75% male) after BAV and 62 control subjects matched to the age and heart rate were prospectively evaluated. The 2D STE assessment of LV longitudinal and circumferential strain and strain rate was performed. Left ventricular eccentric hypertrophy (LVEH) was diagnosed in 75% of patients in the study group. Left ventricular ejection fraction (LVEF) was normal in all patients. In study group, global longitudinal strain (GLS), global longitudinal strain rate (GLSr) were significantly lower compared with the controls: GLS (-19.7±2.22% vs. -22.3±1.5%, P< 0.001), GLSr (-0.89±0.15/s vs. -1.04 ±0.12/s, P < 0.001). Regional (basal, middle and apical segments) strain and strain rate were also lower compared with control group. Global circumferential strain (GCS), global circumferential strain rate (GCSr) as well as regional (basal, middle and apical segments) strain and strain rate were normal. Multivariable logistic regression analysis included: instantaneous peak systolic Doppler gradient across aortic valve (PGmax), grade of aortic regurgitation (AR), left ventricular mass index (LVMI), left ventricular relative wall thickness (LVRWT), left ventricular end-diastolic diameter (LVEDd), peak systolic mitral annular velocity of the septal and lateral corner (S’spt, S’lat), LVEF before BAV and time after BAV and showed that the only predictor of reduced GLS was LV eccentric hypertrophy [odds ratio 6.9; (95% CI: 1.37–12.5), P = 0.045]. Conclusion Patients at long-term observation after BAV present the subclinical LV systolic impairment, which is associated with the presence of its remodeling. Longitudinal deformation is the most sensitive marker of LV systolic impairment in this group of patients.

<p><strong>Aim</strong>. Rheumatoid arthritis (RA) shows a high risk for cardiovascular disease, including heart failure. Although TNF-α has been implicated in the pathogenesis of myocardial remodelling, TNF-α inhibition did not show any efficacy in patients with advanced heart failure and should be contraindicated in RA with cardiac complications. We aimed to assess global left ventricular (LV) systolic function using global longitudinal strain (GLS) as a measure of myocardial deformation, in a group of RA patients before and during anti-TNF-α treatment. <strong>Methods</strong>. 13 patients (female:male 7:6) affected by RA were prospectively followed for one year during anti TNF-α treatment. Every subject underwent echocardiography before starting anti-TNF-α drugs and after one year of treatment, to evaluate LV ejection fraction (EF), telediastolic diameter, telediastolic volume and global longitudinal strain (GLS) that was calculated using 2D speckle tracking as the mean GLS from three standard apical views (2, 3 and 4 -chambers). The patients showed a mean age of 43 years at RA onset (SD: 13) and a mean follow-up of 7.3 years (SD: 4.8). Steroid and methotrexate were used in 84.6% and 100%, respectively, in association with etanercept (6 cases), adalimumab (4 cases) and infliximab (3 cases). <strong>Results</strong>. Patients globally showed a normal EF before and after one year of treatment (mean: 65% and 65.7%, respectively). GLS did not differ before or after anti-TNF-α treatment (mean: -15.8% and -16.7%, respectively). <strong>Conclusion</strong>. Anti-TNF-α treatment did not significantly modify myocardial contractility after 12 months.</p><p> </p><p> </p>

Abstract Purpose To confirm GLS diagnostic sensitivity as parameter for the evaluation of LV systolic function in women with breast cancer who underwent chemotherapy including anthracyclines and to identify a pattern of decreased 2D speckle tracking regional longitudinal strain through the analysis of polar maps obtained with AFI technology. Methods We enrolled 60 female patients (age with 56.5±12 years) with breast cancer before the beginning of chemotherapy. The study protocol included clinical examination, ECG with QTc calculation, lab test (BNP and troponin I) and echocardiography with TDI and speckle tracking analysis (STI), that were performed before the beginning of the chemotherapy (basal) and after 3, 6 and 12 months. Echocardiography evaluation included the following parameters: LV end-diastolic and end-systolic volumes, LV ejection fraction (EF), average TDI S' at the mitral annulus, Global Longitudinal Strain (GLS), regional longitudinal strain, E/A ratio, E/E' ratio and sPAP. For each patient we analyzed the bull's eye maps before the beginning of the therapy (basal value) and when GLS showed the lowest values during the FU (FU value), to identify the pattern of regional longitudinal strain alterations. We compared basal and FU strain values for each of the 17 LV segments and the difference between them (delta) was calculated according to the formula [(FU LS –basal LS, (%)]. Results During the FU, systolic blood pressure, systolic pulse pressure and BNP values increased from the basal assessment to the 3 and 6 months FU. Similarly, a progressive worsening of GLS values has been observed (basal −20.4±2.6%, 3 months FU −18.2±2.5%, 6 months FU −17.7±2.9, 12 months FU −17.6±3, p value <0.001). Through the analysis of polar maps, we observed that regional strain values worsened significantly in all the LV segments but the most evident impairment was reported in the apical cap (−22.8±3.9 vs −17.1±3.8; p<0.001, Δ=−5,78%) and in the apical segment of the anterior interventricular septum (−23.4±4.5 vs −17±6.3; p<0.001, Δ=−6,2%), as reported in Figure. Conclusion GLS is able to identify LV systolic dysfunction that EF is not able to detect. However, since that it describes the global function of LV, GLS could result as normal (18–20%) when strain impairment of some LV segments is counterbalanced by the compensatory strain increase of other segments, determining an misdiagnosis of myocardial damage. Regional strain and particularly the Δ-strain, seem to suggest that anthracyclines induce a damage more evident in the apical cap and in the apical segment of the interventricular septum and this pattern could be typical in these patients. Thus, polar maps analysis could be provide additional information about cardiac damage in this population.

Background Early detection of subclinical left ventricular (LV) systolic dysfunction in hypertensive patients is important for the prevention of progression of hypertensive heart disease. Methods We studied 60 hypertensive patients (age ranged from 21 to 49 years, the duration of hypertension ranged from 1 to 18 years) and 30 healthy controls, all had preserved left ventricular ejection fraction (LVEF), detected by two-dimensional speckle tracking echocardiography (2D-STE). Results There was no significant difference between the two groups regarding ejection fraction (EF) by Simpson's method. Systolic velocity was significantly higher in the control group, and global longitudinal strain was significantly higher in the control group compared with the hypertensive group. In the hypertensive group, 23 of 60 patients had less negative global longitudinal strain than −19.1, defined as reduced systolic function, which is detected by 2D-STE (subclinical systolic dysfunction), when compared with 3 of 30 control subjects. Conclusion 2D-STE detected substantial impairment of LV systolic function in hypertensive patients with preserved LVEF, which identifies higher risk subgroups for earlier medical intervention.

Abstract Background Functional single ventricle (FSV) is a spectrum of severe congenital heart disease, with multiple anatomic variations but similar surgical treatment strategies. FSV patients are living longer into adulthood compared to two or three decades ago, and they are more frequently undergoing imaging to assist in clinical and surgical management. Objective To determine impact of ventricular morphology on myocardial deformation in patients with single ventricle. Material and Methods From November 2017 to July 2018, 41 patients with single ventricle morphology or Physiology who were referred to Ain-Shams University hospitals for follow up Echocardiography or diagnostic cardiac catheterization were enrolled in the study.All patients subjected to history, clinical examination Echocardiography (conventional 2D and speckle tracking “global longitudinal strain and strain rate”.Dominant ventricular strain was analyzed using conventional two-dimensional echocardiographic. The region of interest was obtained by tracing the dominant ventricle endocardial borders at end-systole. An automated software program was used to calculate the frame-to-frame displacements of speckle pattern within the region of interest throughout the cardiac cycle. Results There is statiscially significance between the basic anatomy of the single ventricle and the ejection fraction (p value 0.001) and global longitudinal strain pattern by speckle tracking echocardiography with (p value 0.031) with no statistically effect of the side of dominance. Conclusion: Regarding the side of dominant ventricle there is no significant relation between the side of dominant ventricle on myocardial deformation (by ejection fraction, global strain and strain rate by speckle tracking echocardiography) but there is significant relation between the ventricular morphology and the myocardial deformation that was assessed by by the ejection fraction and global longitudinal strain (by speckle tracking echocardiography) but with no significant effect on the strain rate (by speckle tracking echocardiography)

Abstract Aim To evaluate the ability of Speckle Tracking Echocardiography (STE), as compared to Cardiac Magnetic Resonance (CMR), in identifying acute and sub-acute abnormalities in systolic function occurring with focal myocarditis in children and adolescents without evident wall motion abnormalities. Methods: We analyzed data from 33 consecutive patients (age 4-17year) with CMR-confirmed focal myocarditis and without regional motion abnormalities and/or reduced ejection fraction. Patients underwent echocardiography with analysis of regional and global longitudinal strain and CMR for the identification of focal edema and myocardial fibrosis. Impaired longitudinal strain was defined according to previously reported age-specific reference values. Results: Despite normal ejection fraction at admission, prevalence of impaired systolic function by STE was present in 58% of patients (n = 19). Reduction in longitudinal strain was regionally related to CMR-identified edema areas, with lowest values found at the level of the infero-lateral segments as compared to the mean of the other segments (p &lt; 0.05). Amount of CMR-edema was strongly correlated with impairment of STE (r=-712; p = 0.01). At follow-up, significant improvement in global longitudinal strain could be observed in all patients (p &lt; 0.001) with STE normalization recorded in 13 of 19 patients. Persistent regional impairement in STE could however still be found 6 patients, consistent with residual focal cardiac fibrosis at follow-up CMR. Conclusion: In children and adolescents with focal myocarditis, STE identifies subclinical abnormalities in systolic function, consistent with regional edema at CMR. In addition, analysis of STE provides insights in the identification of regional recovery or persistent systolic impairment, possibly due to residual focal fibrosis. Abstract P828 Figure.
