echocardiographic assessment of functional mitral regurgitation

WebMethods and results: Eighty-three patients with at least mild MR underwent 2D and 3D echocardiography. Direct planimetry of VCA was performed by 3D echocardiography. Two-dimensional quantification of MR included 2D ROA by proximal isovelocity surface area (PISA) method, vena contracta width, and ratio of jet area to left atrial area. WebValues <0.3 cm are consistent with mild MR and >0.7 cm with severe MR. Intermediate values require further quantitative methods to define MR severity.7 In cases of circular MR, VC width correlates with effective regurgitant orifice area (EROA), but in cases where RO is not circular VC width may underestimate MR severity . Another limitation is ... WebDescription of the PISA data files. The main data files are the student, the school and the cognitive datasets. These data files are available for each PISA cycle (PISA 2000 – PISA 2015).
