BACKGROUND In adults, tissue Doppler imaging (TDI) is a recommended component of routine echocardiography. However, TDI velocities are less accepted in pediatrics, due to their strong variability and age dependence in children. This study examines the distribution of myocardial tissue Doppler velocities in healthy children to assess the effect of age with cardiac growth on the various echocardi...

Tissue Doppler Echocardiography was introduced in the 1960s (Yoshida et al., 1961), and enabled the quantitative assessment of myocardial motion and deformation. The wide use of tissue Doppler as a research tool halted, however, until the early 1990s (Hatle & Sutherland, 2000). Tissue Doppler is now available for high frame rates, wide sector angles and in combination with 2-dimiensional data a...

A middle-aged African lady, who presented with ventricular tachycardias, mitral valve regurgitation and congestive heart failure, was diagnosed with cardiac sarcoidosis. Tissue Doppler imaging demonstrated abnormalities suggestive of myocardial scar, which was confirmed by contrast-enhanced cardiac magnetic resonance.

Nowadays, chronic congestive heart failure (CHF) remains a challenge despite significant progress in drug therapy. Cardiac resynchronization therapy (CRT) has revolutionized CHF treatment as a result of improved cardiac function based on optimal drug therapy [1, 2]. However, approximately 18% to 32% of patients who have undergone CRT do not experience positive curative effects [3, 4]. Recent st...

BACKGROUND Doppler echocardiographic studies of the left ventricle (LV) function in patients with β-Thalassemia Major (β-TM) had shown different patterns of systolic and diastolic dysfunctions associated with abnormal serum brain natriuretic peptide (BNP). AIM This cross-sectional study was designed to study the LV systolic and diastolic functions and correlate that with serum level of N-term...

BACKGROUND Right ventricular dysfunction has been observed in uremic patients receiving percutaneous transluminal angioplasty (PTA). This prospective study focuses on the impact of tissue Doppler imaging echocardiographic parameters on assessing right ventricle function in uremic patients post PTA of dysfunctional hemodialysis access. METHODS Sixty uremic patients were divided into two groups...

Essential hyperhidrosis is a well recognized dermatologic and neurologic disorder, characterized by excessive sweating of the eccrine sweat glands. It is also associated with cardiac autonomic dysfunction because sympathetic fibers to eccrine glands of palms of the hand arise from stellate and upper thoracic ganglia, which also innervate the heart. In this study, we investigated cardiac functio...

AIMS The aim of this study was to determine the utility of pulsed wave Doppler tissue imaging in the evaluation of regional left ventricular diastolic function in patients with ischaemic heart disease. METHODS AND RESULTS In 30 normal subjects and 43 patients with ischaemic heart disease, Doppler tissue imaging was performed in each of the 16 segments of the myocardium. The following diastoli...

A diastolic dysfunction (DD) assessment algorithm may seem simple to apply however, it is not always straightforward. Flow-derived parameters define the behavior of the chamber in its entirety. These parameters are unfortunately preload sensitive. Furthermore, in the perioperative period patients are not under ambulatory conditions. Examinations under anesthesia and positive pressure ventilatio...
