Wide Clinical Application

Transthoracic echocardiography is the most frequently used method for detection of impaired contractility of the left ventricle. In most cases, assessment of contractility is carried out visually “by eye”, what increases its subjectivity, is operator-dependent in nature and requires a high level of clinical training and experience of the researcher. Currently in the arsenal of a specialist in echocardiography for quantification of left ventricular contractility sometimes is used tissue Doppler echocardiography, however, this method requires special settings of the image (high frame rate, the allocation of zones of interest), depends on the scanning angle and on operator qualification, has high intra – and inter-operator variability, and significantly increases the duration of the study. Therefore, this method has not received wide clinical application. In the 2000s years an innovative technique of speckle tracking emerged, which, unlike tissue Doppler echocardiography is efficient, does not burden a researcher with time costs, has a low intra – and inter- operator variability, does not depend on scan angle. In recent years, this technology is actively implemented in clinical practice for detection of subclinical impairment of the functional state of the myocardium in different diseases and syndromes: arterial hypertension, ischemic heart disease, valvular defects, and congenital heart disease, heart failure, cardiomyopathy of different etiology.

AbstractBackground:This study evaluated cardiac function using tissue Doppler echocardiography and assessed electrocardiographic findings in children diagnosed with Wilson’s disease.Method:Asymptomatic patients with a diagnosis of Wilson’s disease (n = 43) were compared to healthy controls (n = 37) that were age and gender matched.Results:The standard electrocardiographic and conventional echocardiographic examinations were similar in both groups. The left ventricular ejection fraction, shortening fraction, and diastolic function were not significantly different between the two groups. The Tei index for mitral lateral, mitral septal, tricuspid lateral, tricuspid septal, and inter-ventricular septum on tissue Doppler echocardiography was higher in the patient group, yet it did not reach statistical significance. Mitral lateral and septal systolic annular velocity values were significantly lower in the patient group when compared to the control group (p = 0.02 and 0.04, respectively). Also, mitral lateral and septal isovolumetric contraction time values were higher in the patient group (p = 0.04). Although the left ventricular values were not significantly different, relative left ventricular wall thickness was higher in the patient group when compared to the control group, and concentric remodelling in the left ventricle was found in 7 (16%) of 42 patients. QT interval (p = 0.02) and P-wave dispersion values (p = 0.04) were significantly higher in the patient group compared to the control group, and these tend to predict arrhythmias.Conclusion:Our study based on the tissue Doppler echocardiography assessment indicated a subclinical systolic, rather than diastolic, dysfunction in the myocardium with increased QT interval and P-wave dispersion, despite the young age of the patients and short disease duration.
