A computer algorithm has been developed for segmentation and three-dimensional (3D)
reconstruction of Doppler color-flow images. The algorithm enables the user to select a …

We compared color Doppler flow mapping data to angiographic data in 294 patients with
suspected valvular regurgitation. Thirty-one patients had rheumatic mitral regurgitation and …

The proximal flow convergence method of multiplying color Doppler aliasing velocity by flow
convergence surface area has yielded a new means of quantifying flow rate by …

Intraoperative two-dimensional echocardiography is a new diagnostic and monitoring
technique that provides immediate information, unavailable from routine hemodynamic …

Purpose Analysis of mitral valve morphology during reconstruction is routinely based on
visual assessment and subjective, poorly reproducible measurements. We prove the …

Objectives. This study sought to investigate the applicability of a current implementation of a
three-dimensional echocardiographic reconstruction method for color Doppler flow …

Surgical mitral valve repair remains the gold standard treatment of mitral regurgitation due to
degenerative disease. Surgery is performed on the quiescent heart; therefore, assessments …

We evaluated 147 patients with adequate color Doppler and angiographic studies for mitral
regurgitation. Sixty-five patients had no mitral regurgitation by both color Doppler and …

Color Doppler imaging provides information on spatial distribution of blood flow and is
widely used to evaluate valvular regurgitation and shunt lesions. Estimates of size and …

T wo-dimensional color flow mapping has proven valuable for estimating the magnitude of
valvular regurgitation. I.* Recent studies3-5 have proposed analyzing the flow convergence …
