ResumoDecisions regarding surgery for mitral regurgitation (MR) are predicated on the accurate quantification of MR severity. Quantitative parameters, including vena contracta width, regurgitant volume and fraction, and effective regurgitant orifice area have prognostic significance and are recommended to be obtained from patients with more than mild MR. New tools for MR quantification have been provided by 3-dimensional echocardiography, cardiac magnetic resonance, and cardiac computed tomography, but limited guidance on appropriate image acquisition and post-processing techniques has hindered their clinical application and reproducibility. This review describes optimal image acquisition and post-processing methods for quantification of MR.
