Benefit of 3D Vena Contracta Area over 2D-Based Echocardiographic Methods in Quantification of Functional Mitral Valve Regurgitation

Diagnostics, 2023
Background: The two-dimensional proximal isovelocity surface area (2D PISA) method in the quantification of an effective regurgitation orifice area (EROA) has limitations in functional mitral valve regurgitation (FMR), particularly in non-circular ...

Novel 3-dimensional effective regurgitation orifice area quantification serves as a reliable tool to identify severe mitral valve regurgitation

Scientific Reports
A precise quantification of mitral regurgitation (MR) severity is essential for treatment and outcome of patients with MR. 3D echocardiography facilitates estimation of MR but selection of patients with necessity of invasive treatment remains challenging.

Three-Dimensional Transesophageal Echocardiographic Vena Contracta Area for Grading Mitral Regurgitation: Severity Cut-offs From a Prospective Tunisian Cohort. [PDF]

Echocardiography
Three‐dimensional vena contracta area (VCA) measured by transoesophageal echocardiography enables precise accurate quantification of mitral regurgitation severity. In a Tunisian cohort, 3D VCA showed strong correlations with conventional 2D indices and excellent diagnostic performance for severe MR, supporting its use particularly in rheumatic mitral ...

Intraoperative comparison of 2D versus 3D transesophageal echocardiography for quantitative assessment of mitral regurgitation

Annals of Cardiac Anaesthesia, 2021
Background: Effective regurgitant orifice area (EROA) can be represented by 3D echocardiographic vena contracta cross-sectional area (3D-VCA) as a reference method for the quantification of mitral regurgitation (MR) without making any geometrical ...
