“…Nevertheless it is reported that similar results with colored Doppler could be obtained (1). With the measurement of tissue displacement, in other words tissue tracking imaging, the visual and quantitative amount of tissue motion can be interpreted in millimeters-centimeters in a relatively easier way (33)(34)(35)(36). As strain and strain rate imaging are not affected by impulsion-traction and translation, they may provide better differentiation of mechanical delay (37,38).…”

Objective: The aim of this study was to prospectively evaluate the effect of percutaneous coronary intervention in the acute period on left ventricular dyssynchrony in ST-segment elevation myocardial infarction patients by using Tissue Synchronization Imaging. Methods: Forty-four ST-segment elevation myocardial infarction (MI) patients (29 male, 15 female), who were admitted within the first 12 hours of chest pain symptoms, were enrolled in the study. According to the localization of MI, the patients were divided into groups as anterior MI (n=26) and inferior MI (n=18). All echocardiography measurements were taken just before percutaneous coronary intervention (PCI) and following PCI at a mean of 3-6 days. They were assessed according to the time to reach the peak systolic velocity, which was calculated by the tissue synchronization imaging method from four pairs of non-apical alternate segments. The difference between the duration to reach the peak systolic velocity in alternate segments was regarded as left ventricle dyssynchrony and the results were compared. Results: In the anterior MI group, basal anterior (p<0.01), mid-anterior segment (p<0.01) and basal septal segment (p<0.01); in the inferior MI group, the basal septal segment (p=0.02), mid-septal segment (p=0.02), and basal and mid-inferior segment (p<0.01) values were significantly lower in the post-PCI measurements when compared to the measurements taken prior to PCI. In both groups, the intraventricular dyssynchrony indices of the basal anterior-basal inferior (p<0.01), mid-anterior-mid-inferior (p<0.01) segments were found to be significantly lower in the post-PCI period when compared to the pre-PCI period. Conclusion: It was found that percutaneous coronary intervention in patients with ST-elevation significantly decreases the degree of LV dyssynchrony in the acute period.

“…[13] published an analysis of several dozens of patients in whom mitral annulus displacement was measured in three apical views -a total of 6 tissue velocity measurements using TDI with respective measurements using M-mode -in relation to LVEF measurements using the Simpson method (2 apical projections). The authors showed a significant correlation of the measurements obtained using a tissue Doppler and M-mode techniques with LVEF values [13].…”

“…TTI is not noise-sensitive, and has sufficient reproducibility and accuracy, with good spatial and temporal resolution and low inter-and intraobserver variabilities. 9,10 In the present study, we could evaluate ventricular dyssynchrony using TDI and TTI, as well as the relationships between CRBBB and ventricular dyssynchrony and LV cardiac function. Our results were almost identical to those obtained from a study using an electro-anatomical mapping system.…”

ardiac resynchronization therapy (CRT) in patients with advanced heart failure (HF) and a ventricular conduction delay improves symptoms and functional capacity, induces reverse remodeling, and reduces morbidity, and probably mortality. [1][2][3][4] It is well known that although the vast majority of CRT recipients present with left bundle branch block (LBBB), up to 10% of the minority have nonspecific conduction delays or right bundle branch block (RBBB). 2,5 Recently, RBBB was proven to be an important predictor of mortality in patients with congestive HF, just as has LBBB. 6 However, patients with RBBB and congestive HF have not been adequately evaluated because of an under-representation in the referenced studies. Therefore, which type of patients with RBBB has ventricular conduction delays, and thus are good candidates for CRT, has not been fully clarified. Methods Study PopulationThis study included 104 patients (34 women, 70 men; mean age, 59±15 years) who underwent conventional echocardiography, including tissue Doppler imaging (TDI) and tissue tracking imaging (TTI) between January 2002 and December 2004. Of these, 49 consecutive patients had complete RBBB (CRBBB) with a duration of the QRS complex of ≥120 ms (RBBB-Gr). The remaining 55 had normal morphology of the QRS complex and narrow QRS (<120 ms; Control-Gr), and were randomly selected so that the data collected would be statistically matched to the RBBB-Gr patients in terms of age and gender (Table 1). In total, 33 patients had hypertension, 5 dilated cardiomyopathy, 5 mitral valvular diseases, 2 hypertrophic cardiomyopathy, 1 congenital heart disease, 3 ischemic heart disease, and the remaining 93 (89%) had no structural heart disease. Echocardiography demonstrated that the mean left ventricular ejection fraction (LVEF) was 64.2±11.8% (range, 12-83), and left ventricular end-diastolic diameter (LVEDD) 46.5± 8.5 mm (range, 34-75). All patients were in sinus rhythm, and the mean QRS duration was 113.8±33.3 ms (range, 70-200). All patients in the Control-Gr had LVEF >50% (range, 51-83). Echocardiographic Examination Including TDI and TTIThe left ventricular (LV) dimensions were measured by M-mode echocardiography in the parasternal long-axis view. The LVEDD was measured at the onset of the QRS Background The indications and efficacy of cardiac resynchronization therapy (CRT) have not been sufficiently clarified in patients with right bundle branch block (RBBB). Methods and ResultsThis study included 55 patients with normal QRS morphology and duration (ControlGr) and 49 patients with complete RBBB (CRBBB-Gr). Using tissue Doppler imaging, the time difference (TD) between the electromechanical delay of the septal wall, left ventricular (LV) lateral wall, and right ventricular free wall were measured. Using tissue tracking imaging, the coefficient of the time variation from the beginning of the QRS to the peak displacement time of 6 regions of the LV (CV-PMDLV) was calculated. The TD between the septal wall and that of the LV lateral wall (TDSEPT-LAT)...
