Multimodality Imaging of Mitral Regurgitation.

Mitral regurgitation (MR) is a common valvular pathology and is widely known to cause morbidity and mortality. Quantification of MR severity is critical for determining surveillance strategies and to guide timing of procedural intervention. There are numerous ways to quantify regurgitant volume, each with their own strengths and weaknesses. In this article, we review multimodality imaging of the mitral valve and explore the most common and widely used imaging modalities and methods to evaluate MR severity.
