Assessment of Mitral Regurgitation Severity by Doppler Color Flow Mapping of the Vena Contracta in Dogs
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 mapping remains elusive. We hypothesized that vena contracta width by color flow mapping would accurately predict the severity of MR. METHODS AND RESULTS We studied 80 patients with MR. Vena contracta width was measu...
متن کاملColor Doppler regurgitant jet area for evaluating eccentric mitral regurgitation: an animal study with quantified mitral regurgitation.
OBJECTIVES The purpose of the present study was to rigorously evaluate the accuracy of the color Doppler jet area planimetry method for quantifying chronic mitral regurgitation. BACKGROUND Although the color Doppler jet area has been widely used clinically for evaluating the severity of mitral regurgitation, there have been no studies comparing the color jet area with a strictly quantifiable ...
متن کاملDiagnostic value of vena contracta area in the quantification of mitral regurgitation severity by color Doppler 3D echocardiography.
BACKGROUND Accurate quantification of mitral regurgitation (MR) is important for patient treatment and prognosis. Three-dimensional echocardiography allows for the direct measure of the regurgitant orifice area (ROA) by 3D-guided planimetry of the vena contracta area (VCA). We aimed to (1) establish 3D VCA ranges and cutoff values for MR grading, using the American Society of Echocardiography-r...
متن کاملQuantification of tricuspid regurgitation by measuring the width of the vena contracta with Doppler color flow imaging: a clinical study.
OBJECTIVE We sought to evaluate the vena contracta width (VCW) measured using color Doppler as an index of severity of tricuspid regurgitation (TR). BACKGROUND The VCW is a reliable measure of mitral and aortic regurgitation, but its value in measuring TR is uncertain. METHODS In 71 consecutive patients with TR, the VCW was prospectively measured using color Doppler and compared with the re...
متن کاملAssessment of severity of aortic regurgitation using the width of the vena contracta: A clinical color Doppler imaging study.
BACKGROUND The width of the vena contracta (VC-W), the smallest area of regurgitant flow, reflects the degree of valvular regurgitation and is measurable by color Doppler imaging, but this method has not been validated in aortic regurgitation (AR). METHODS AND RESULTS We prospectively examined 79 patients with isolated AR and 80 patients without regurgitation. The VC-W was measured from the l...
