BACKGROUND Assessment of the right ventricular (RV) function by echocardiography in patients with pulmonary thromboembolism (PTE) is complex and frequently qualitative. Tissue Doppler has been used for the semiquantitative assessment of this chamber, although with some limitations. OBJECTIVE To evaluate RV function in PTE using tissue-Doppler echocardiography, in addition to atrial natriureti...

the aim of this article is to review the application of current imaging techniques used for the detection of viable myocardium. each technique is discussed briefly, and the more commonly used techniques are compared. the imaging techniques reviewed herein are dobutamine stress echocardiography, single photon emission tomography, magnetic resonance imaging, positron emission tomography with f-18...

Assessment of mitral annular tissue velocity plays an essential role in the evaluation of diastolic dysfunction. We have previously shown that mitral annular velocities can be derived from standard four-chamber cine SSFP images by automatically detecting and tracking the mitral valve insertion points [1]. However, this method has not been validated against tissue Doppler echocardiography, the s...

Objective: To assess the effect of asthma in children on systolic and diastolic functions heart, to explore relationship between two.Methods: The case-control study was conducted at Kafrelsheikh University Hospital, Egypt, from September 2019 May 2022, comprised asthmatic either gender aged 5-15 years healthy controls matched for age gender. participants were subjected detailed history, complet...

BackgroundAsthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. We aimed to investigate Right Ventricular (RV) functions in asthmatic children by conventional and tissue Doppler echocardiography (TDE).Materials and Methods Pulmonary function tests, con...

Assessment of diastolic function and left ventricular filling pressures in the setting of both normal and reduced systolic function is of major importance particularly in patients with dyspnea. Since multiple echocardiography parameters are used to assess diastolic function each with some limitations, a comprehensive approach should be applied. Transmitral Doppler flow should be evaluated in co...

OBJECTIVE To assess prognosis of pulmonary thromboembolism using tissue Doppler echocardiography and brain natriuretic peptide. METHODS Patients aged over 18 years were evaluated within 24 hours of confirmed diagnosis (chest tomography/pulmonary scintigraphy) of pulmonary embolism using two-dimensional echocardiography and tissue Doppler for right ventricular systolic (s') velocities, strain,...

modifications and medical interventions could prevent or delay the subsequent development of heart failure in Diabetic patients. Conventional echocardiography was used to screen for and diagnose left ventricular diastolic dysfunction-LVDDbut the results was not satisfactory and underestimate the magnitude of LVDD due to the pseudonormal pattern in grade 2 diastolic dysfunction. Tissue Doppler i...

Accurate quantification and timing of regional myocardial function allows early identification of dysfunction, and therefore becomes increasingly important for clinical risk assessment, patient management, and evaluation of therapeutic efficacy. For this purpose, the application of tissue Doppler echocardiography has rapidly increased. However, echocardiography has some major inherent limitatio...
