background and aim: iron overload in patients with thalassemia major is one of the most important complications of this disease and its cardiac complications are the most important causes of death in these patients.mri t2 is the perfect device to assess the amount of iron deposited in the heart of thalassemia patients, but it causes waste of time and also is an expensive diagnostic method. tiss...

background abnormalities in the velocity and pattern of myocardial shortening on tissue doppler imaging (tdi) have been proposed to aid in the noninvasive diagnosis of coronary artery disease (cad). objectives we investigated the diagnostic value of post-systolic shortening (pss), a delayed ejection velocity of the myocardium after the closure of the aortic valve, on tdi in the diagnosis of cad...

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...

introduction:  in order to assess echocardiographic left ventricular functional indices in patients with differentiated thyroid carcinoma (dtc), after l-t4 withdrawal (short-term overt hypothyroidism) and during tsh suppressive therapy, we have evaluated cardiac hemodynamics in a single cohort study. methods: 24 patients with dtc were studied in two phases: 1: at least 4 weeks after l-t4 withdr...

background: we sought to assess right ventricular (rv) systolic and diastolic functions via tissue doppler imaging (tdi) in order to discriminate right-to-left (bidirectional) from left-to-right intracardiac shunts. methods: a tissue doppler velocity study via doppler echocardiography was performed in 20 patients with left-to-right shunt (without evidence of significant pulmonary hypertension) ...

Background:Cystic Fibrosis (CF) is a systemic disease affecting extra pulmonary dysfunction as a result of CF-related lung disease. Because of lack of enough studies in this field and utilization of TDE in this field, we aimed to evaluate t...

Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. <s...

background: the recent developments in tissue doppler imaging (tdi) now more than ever permit the quantification of the myocardial function. in the current systems, tissue tracking or displacement curves are generated from color tissue doppler data through the instantaneous temporal integral of velocity-time curves. methods: the purpose of the present study was to assess regional myocardial dis...
