This study was undertaken to examine whether Doppler color flow imaging could accurately
estimate the valve area in mitral stenosis. Doppler color flow assessments were performed …

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 …

We used Doppler color flow imaging, a new noninvasive technique for mapping of
intracardiac blood flow, to visualize and characterize the blood flow jet in 42 patients with …

Two Doppler methods, the pressure half-time method proposed by Hatle and the method
based on the equation of continuity, were used to estimate stenotic mitral valve area …

Early studies using Doppler color flow imaging have suggested that measurement of the
regurgitant jet area provides information regarding the severity of valvular insufficiency. This …

Assessing the severity of valvular regurgitation can be an important aspect of determining
the appropriate management of individual patients, but this can often prove difficult on …

Doppler echocardiography has been widely used as a noninvasive method to quantify
valvular heart diseases. This study assessed the variability between 2 echocardiography …

Forty-three patients with mitral stenosis (MS) were studied to assess the relation of catheter-
derived pressure gradient half-time (P 1 2), mitral valve areas (calculated by the Gorlin …

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 …

OBJECTIVES.: This study sought to compare the mitral valve areas of patients with
rheumatic mitral valve stenoses as determined by means of four echocardiographic and …
