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. WebMar 1, 2024 · The MR index is a composite score comprising six echocar-diographic parameters—jet length, PISA, CW jet density, pulmonary artery systolic pressure, pulsed wave Doppler, pulmonary vein flow pattern, and LA size. Such scores provide a better overall assessment of MR. Fig. 23.

WebConclusions: Quantitative assessment of functional MR severity by 3D TEE may be superior to 2D methods by permitting more direct measures of PISA. Two-dimensional TEE techniques for assessing functional MR severity that rely on an HS- or HE-PISA shape may underestimate the EROA due to geometric assumptions that do not account for asymmetry.
