OBJECTIVES The purpose of this study was to assess the clinical feasibility of three-
dimensional (3D) reconstruction of color Doppler signals in patients with mitral regurgitation …

Color Doppler echocardiography does not provide adequate information about the severity
of mitral regurgitation in patients with eccentric mitral regurgitation. We have developed a …

Objectives. To determine the influence of jet eccentricity and mechanism of mitral
regurgitation, we examined 1) the relation between jet extent and severity of mitral …

Abstract Aims Colour Doppler is the most widely used technique for assessing valve
disease, but eccentric regurgitant jets cannot be visualized and measured by conventional …

Background: Prior studies have reconstructed mitral regurgitant flow in three dimensions
displaying gray scale renditions of the jets, which were difficult to differentiate from …

Background. Color Doppler echocardiography is a standard technique for assessing mitral
regurgitation before and after mitral valvuloplasty. Mitral valve prolapse produces complex …

Background Recent studies have shown that many instrument and physiological factors limit
the ability of color Doppler total jet area within the receiving chamber to predict the severity …

To determine whether Doppler color flow mapping could be used to quantify changing levels
of regurgitant flow and define the technical variables that influence the size of color flow …

BACKGROUND In clinical color Doppler examinations, mitral regurgitant jets are often
observed to impinge on the left atrial wall immediately beyond the mitral valve. In …

This study was performed to test the hypothesis that measurements of jet area by Doppler
color flow imaging can predict the angiographic severity and hemodynamic consequences …
