The evaluation and care of patients with mitral regurgitation would be facilitated by an easy,
reproducible and noninvasive method that could quantitate the hemodynamic burden. In this …

In an attempt to develop a new approach to the non-invasive measurement of mitral
regurgitation, Doppler echocardiography and left ventriculography were performed in 20 …

Measurements of mitral and aortic valve flows were obtained with two-dimensional Doppler
echocardiography in 25 patients with isolated mitral (n= 19) or aortic (n= 6) regurgitation and …

Sensitivity and specificity of detection of mitral regurgitation was assessed by range-gated
Doppler echocardiography. The degree of mitral regurgitation was also estimated by the …

BACKGROUND Quantitation of valvular regurgitation remains a challenge. The accuracy of
quantitative Doppler is controversial, and its ability to measure regurgitant volume is …

Accurate quantitation of mitral regurgitation offers a major clinical dilemma. The clinical
clues depend largely on cardiac auscultation, the accuracy of which needs to be rigorously …

A noninvasive method to accurately quantitate the severity of mitral insufficiency would be of
major clinical value. In theory, in the absence of confounding variables, regurgitant mitral …

Pulsed Doppler indices were devised in order to grade the severity of mitral regurgitation on
a quantitative basis. Indices were obtained by mapping the regurgitant jet by recording …

Doppler evaluation of mitral regurgitation remains difficult; thus, a head-to-head comparison
of the diagnostic accuracy of Doppler methods was undertaken. Fifty patients with native …

Background Quantitative Doppler echocardiography and proximal flow convergence
methods are validated techniques for quantifying mitral regurgitation. However, the clinical …
