M-mode, two-dimensional and Doppler echocardiography were used to assess the comparative value of each in the detection of clinically diagnosed mitral valve prolapse; 125 consecutive patients with a mid- to late systolic click, with or without a late systolic murmur, were included. There were 46 men and 79 women; their mean age was 42 years. M-mode echocardiography detected 62 of 125 cases (sen...
In the 1980s, the development of Doppler echocardiography, especially pulsed wave Doppler techniques, provided significant progress in determining cardiac flow volumes. The pulsed wave Doppler method is based on a simple mathematical principle, which multiplies a flow area by its velocity during the flow time (velocity–time integral) to estimate a flow volume. This Doppler method assumes a spat...
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...
