While color Doppler flow mapping has yielded a quick and relatively sensitive method for
visualizing the turbulent jets generated in valvular insufficiency, quantification of the degree …

This study evaluates the possible role of the mitral apparatus in left ventricular function after
correction of chronic mitral regurgitation. Seventeen patients underwent complete …

BACKGROUND Analogous to stenotic valve area in the assessment of valvular stenosis,
regurgitant orifice area (ROA) represents a fundamental parameter to assess valvular …

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 …

Echocardiographic studies of the mitral valve were performed in 57 patients with pure or
predominant mitral stenosis who subsequently underwent surgery (30 commissurotomy, 27 …

We studied the possibility that a mitral regurgitant Doppler signal area on a two-dimensional
color Doppler echocardiogram can reflect changes in mitral regurgitant volume in 24 …

Background Although Doppler color flow mapping is widely used to assess the severity of
mitral regurgitation (MR), a simple, accurate, and quantitative marker of MR by color flow …

RESULTS In Table I the pertinent clinical data are sum-marized, and anatomical findings
observed at open heart operation are indicated. The reported auscultatory findings …

Flow rate across an orifice can be determined from color Doppler echocardiographic maps
of the flow convergence region proximal to the orifice. Different methods have been …

From 1986 to 1992 102 mitral valve repairs were done for mitral regurgitation due to a
degenerative disease. Forty-eight patients had an anterior prolapse or prolapse of both …
