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...
The Doppler effect, which occurs on the reflection of ultrasound from moving blood or tissue, is observed as a shift in frequency of the reflected ultrasound from that of the incident ultrasound. This Doppler shift has been widely used in clinical practice as a means of measuring blood velocity. Two types of Doppler Imaging are often discussed as facilities on ultrasonic scanners, namely Colour...
objectives in this study, besides studying the rv function in ssc patients, attempts have been made to find a new possible noninvasive echocardiographic test for early diagnosis of systolic failure as a pah complication. methods 30 patients with at least a 2-year history of diffuse ssc confirmed by an expert rheumatologist were enrolled in this study. all the patients underwent transthoracic ec...
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.
