Fetal cardiac time intervals determined by Doppler echocardiography.
One-hundred and eleven Doppler echocardiographic examinations were performed on 88 normal fetuses, ranging from 16 to 41 weeks of gestation. Aortic and pulmonary maximal velocity (MV), acceleration time (AT), ejection time (ET), MV/AT (acceleration velocity: AV) and AT/ET ratio in systole were assessed on each blood flow velocity waveform. Aortic MV and pulmonary MV correlated well with gestati...
متن کاملTissue Doppler Imaging versus Conventional Echocardiography in Evaluation of Cardiac Functions in Diabetes Mellitus
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...
متن کاملTissue Doppler imaging in cardiac sarcoidosis.
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.
متن کاملPrognostic value of cardiac time intervals measured by tissue Doppler imaging M-mode in the general population.
OBJECTIVE Tissue Doppler imaging (TDI) M-mode through the mitral leaflet is an easy and precise method to estimate the cardiac time intervals. The aim was to evaluate the usability of the cardiac time intervals in predicting major cardiovascular events (MACE) in the general population. METHODS In a large prospective community-based study, cardiac function was evaluated in 1915 participants by...
متن کاملCardiac time intervals by tissue Doppler imaging M-mode echocardiography: reproducibility, reference values, association with clinical characteristics and prognostic implications.
BACKGROUND The preservation of normal cardiac time intervals is intimately related to normal cardiac physiology and function. In the ailing myocardium, the cardiac time intervals will change during disease progression. As left ventricular (LV) systolic function deteriorates, the time it takes for myocardial myocytes to achieve an LV pressure equal to that of aorta increases, resulting in a prol...
