“…5,6 As an advantage to tissue velocity, strain rate imaging acts independently of overall wall motion or motion induced by contraction. The usefulness of these techniques in detecting myocardial abnormalities has been examined in several studies, [7][8][9][10][11][12][13][14] although there are limited measurements in healthy populations to use as reference data. 15,16 Different regions of the myocardium are usually evaluated and quantified independently.…”

issue Doppler imaging has introduced different techniques, allowing regional quantification of the myocardium. This quantification is possible by measuring the velocity, total deformation, and rate of deformation in every individual segment of the myocardium. 1,2 One of these methods is tissue velocity imaging, by which the total amount of tissue movement during systole can be displayed in color to show overall systolic function in one map. 3,4 This method is influenced by overall heart motion and the myocardial tethering effect.Masoumeh Lotfi-Tokaldany, MD, MPH, Shala Majidi, MD, Farahnaz Nikdoust, MD, Zahra Savand Roomi, MD, Mahmood Sheikhfathollahi, PhD, Hakimeh Sadeghian, MD Received April 24, 2012, ORIGINAL RESEARCHObjectives-To quantify the normal peak mean systolic velocities and strain rate parameters in the left ventricle (LV) and right ventricle (RV) and define their regional differences in normal adult hearts.Methods-Sixty-nine healthy volunteers (42% male; mean age ± SD, 30.03 ± 5.35 years) underwent color tissue Doppler and strain rate imaging. The first and second peak mean systolic velocities, peak strain, and strain rate in the systolic ejection phase were determined for 16 LV segments, the apex (17th segment), and 3 RV free wall segments.Results-The first peak mean systolic velocity was measurable in less than 50% of segments in the inferior and septal (-posterior) walls and RV free wall and in greater than 70% of segments of the other LV walls. The first and second peak mean systolic velocities of all LV walls and the RV free wall decreased significantly from the basal to apical region (P < .001).The strain and strain rate in the lateral and anterior walls decreased significantly from base to apex, whereas the anteroseptal and posterior walls were homogeneous. The strain rate in the inferior wall increased remarkably from base to apex, whereas it decreased significantly from the mid level to the apex. The strain in the RV was homogeneous, whereas the strain rate decreased significantly from the mid level to the apex. The apex (17th segment) showed the lowest value for each of the study parameters.Conclusions-Longitudinal velocities decreased from base to apex, whereas deformation measurements did not show uniform patterns in LV walls and the RV free wall. In most cases, there are 1 peak systolic velocity in the inferior and septal (-posterior) walls and 2 peak systolic velocities in the other 4 LV walls.

Özet-Üç boyutlu speckle-tracking ekokardiyografinin (3BSTE) sol ventrikül (SV) volümlerinin, gerimlerinin ve rotasyonel özelliklerinin kantitatif değerlendirmesinde güveni-lir ve uygulanabilir bir yöntem olduğu kabul edilmiştir. Bu yazıda SV anevrizmasının volümetrik ve fonksiyonel değer-lendirmesinde 3BSTE'nin tanısal önemi vurgulandı.Summary-Three-dimensional speckle-tracking echocardiography (3DSTE) is accepted as a reliable and feasible method in the quantification of left ventricular (LV) volumes, strains and rotational characteristics. This case aimed to demonstrate the diagnostic importance of 3DSTE in volumetric and functional assessment of an LV aneurysm.

“…Although the individual left ventricular (LV) segments have their own specific motion and characteristics, the conclusions of these studies were focused on the overall changes of the LV myocardial walls. In our previous reports, we compared the velocity and deformation indices of inferobasal non-viable akinetic (9) and aneurismal (10) imaging and strain rate imaging parameters decreased significantly and the range of peak systolic strain rate (SR) for the non-viable akinetic segment did not overlap with that of the normal segments. There was no overlap in the peak systolic strain (ST) and SR between aneurismal and normal inferobasal segments (10).…”

Introduction:The use of tissue velocity and strain rate imaging is proposed for the quantification of non-viable myocardium. This study is aimed at investigating the differences in tissue velocity and strain rate imaging indices between non-viable left ventricular apical segments and the normal segments using segment-by-segment comparison. Materials and Method: Thirty-two patients with akinetic left ventricular apical segments and without viability were selected using two-dimensional echocardiography and dobutamine stress echocardiography; 32 individuals with normal echocardiography and coronary angiography formed the normal group. Peak systolic velocity, peak systolic strain, and strain rate were measured in the four left ventricular apical segments and the apex 17 th segment. Results: The patient group had a significantly lower ejection fraction (26.88±6.06% vs. 56.56±2.36%; p<0.001). Overall, the patient group had significantly lower resting peak systolic velocity, systolic strain, and strain rate. In the segmentby-segment comparison, only systolic strain showed a remarkable reduction in the patient group, while reduction in Sm and strain rate were not significant in all the segments. After dobutamine stress echocardiography, only systolic strain showed an insignificant increase compared to the resting values. In the apex 17 th segment, Sm showed significant reduction in the patient group. Conclusion: The ST in apical segments may be used as a quantitative index for detecting akinesia both at rest and after dobutamine infusion. Reduction in Sm can be used as a marker of akinesia in the apical cap at rest.
