Background Celiac disease (CD) is an autoimmune mediated gluten sensitive enteropathy and characterized by a wide range of clinical manifestations. The study aimed to compare Doppler tissue echocardiography findings between children with celiac disease and healthy children. Materials and Methods This case-control study was performed on 186 celiac and healthy children aged 6- 19 years. Celiac d...
BACKGROUND The main purpose of this study is to determine the correlation of inter- and intraatrial conduction times between the electrophysiological and tissue Doppler echocardiographic measurements, and to evaluate the appropriateness of tissue Doppler echocardiography for this measurement. METHODS One-hundred and one patients were included in the study who underwent electrophysiological st...
Background: Estimation of Left Ventricular End Diastolic Pressure (LVEDP) among patients with Mitral Stenosis (MS) helps to diagnose diastolic dysfunction and to explain their symptoms. However, Conventional Doppler measurements have limitation in predicting of LVEDP. This study sought to establish whether the correlation between measurements derived from Tissue Doppler echocardiography and LVE...
In this study, a method for non-invasive estimation of stress on the heart wall in the diastole phase is presented using ultrasound echocardiography and tissue Doppler imaging. The aim of this study was to evaluate the stress on the heart wall as a pre-diagnosis to identify people with coronary artery stenosis. 29 patients with stenosis of more than 70%, 30 patients with stenosis of 50 to 7...
Background and purpose: Atrial fibrillation (AF) is a major cause of mortality and morbidity in patients after coronary artery bypass graft (CABG). Attempt for knowing indices and factor influence post CABG AF may help in finding patients at risk and prevent more complications. This study aimed to evaluate the association between diastolic dysfunction indices and grading with post CABG AF durin...
conclusions the vibratory innocent murmur is associated with the presence of left ventricular false tendon and higher left ventricular outflow tract velocity. the presence of the left ventricular false tendon was somewhat associated with decreased early diastolic myocardial velocity. normal left ventricular systolic and diastolic function can be used as a reassurance in cases with the vibratory...
Background: Echocardiographic findings of Tetralogy of Fallot (TOF) are diagnostic in infants and young children, and echocardiography may be the only examination required prior to surgery. Global left ventricular function determined by conventional Doppler may be normal in these patients; but regional myocardial function assessment by tissue Doppler if abnormal in these patients may affect out...
Objective- to determine the range of systolic times intervals using Pulsed-wave Doppler and m-mode echocardiography in normal, healthy Great Dane dogs. Design- Descriptive study. Animals- Thirty healthy Great Dane dogs. Procedures- This study examined 30 clinically healthy Great Dane dogs by the twodimensional, M-mode and Pulsed-wave Doppler echocardiography. The dogs were awake and unsedated. ...
Background and purpose: Anthracycline is a topoisomerase-interacting agent that is used in treatment of many cancers. We investigated the effects of anthracycline in adults using conventional echocardiography and pulse tissue Doppler imaging. Materials and methods: This observational before-after study was performed in 35 patients being recently diagnosed with cancer for whom ANT therapy was...
