Direct visualization of regurgitant orifice by CMR reveals differential asymmetry according to etiology of mitral regurgitation.

JACC: Cardiovascular Imaging, 2011
ObjectivesThis study sought to characterize the shape of regurgitant orifice area (ROA) and mitral apparatus in various forms of mitral regurgitation (MR) by cardiac magnetic resonance (CMR).BackgroundROA is an accepted parameter of MR severity. However,
