Abstract

The accurate quantification of mitral regurgitation (MR) using 2D imaging tools is difficult due to its structural complexity; however, it is crucially important in clinical medicine as MR severity has prognostic consequences. Novel 3-dimensional (3D) echocardiography and 3-dimensional (3D) color Doppler methods can provide quantitative and qualitative classification of MR including measurement of the vena contracta area, regurgitant volume, regurgitant fraction, and effective regurgitant orifice area (EROA). Nevertheless, with so many conventional and developing techniques it can be difficult to decide which technique to use for selected patients. We suggest using an approach that is focused not only on the techniques and measurements but also combines imaging portability, availability, clinical efficiency, and accurate and reproducible assessments. In this review we discuss the established and emerging applications of 3D color Doppler for the quantification of MR severity.
