Snippet: Conclusions: 3DE assessment of the canine MV is feasible. Morphologic changes associated with MMVD progression are presented. Effective regurgitant orifice area (EROA), calculated from a 1dimensional measurement of the width of vena contracta (VC) as the narrowest portion of the proximal regurgitant jet, might be used to estimate severity of mitral regurgitation (MR). However, this simplified assumption only holds when the EROA is circular, which.....
Document: Conclusions: 3DE assessment of the canine MV is feasible. Morphologic changes associated with MMVD progression are presented. Effective regurgitant orifice area (EROA), calculated from a 1dimensional measurement of the width of vena contracta (VC) as the narrowest portion of the proximal regurgitant jet, might be used to estimate severity of mitral regurgitation (MR). However, this simplified assumption only holds when the EROA is circular, which might not be true in dogs with myxomatous mitral valve disease (MMVD). The aim of the study was to compare measured EROA using color Doppler real-time 3 dimensional echocardiography (RT3D) with calculated EROA estimated by 2 dimensional echocardiography (2D) in 4 chamber (4ch) and 2 chamber (2ch) views of the left ventricle (LV) in dogs with MMVD.
