Quantification of left ventricular remodeling in response to isolated aortic or mitral regurgitation
Journal of Cardiovascular Magnetic Resonance, 2010 Background The treatment of patients with aortic regurgitation (AR) or mitral regurgitation (MR) relies on the accurate assessment of the severity of the regurgitation as well as its effect on left ventricular (LV) size and function.

Automated quantification of mitral valve tenting volume in functional mitral regurgitation by three‐dimensional echocardiography [PDF]
Echocardiography, 2020 AbstractBackgroundTenting of the mitral leaflets is a major pathophysiological factor contributing to functional mitral regurgitation (FMR). A novel software tool allows automated quantification of the tenting volume (TnV) by 3D transesophageal echocardiography (TEE).

Comparison of mitral regurgitant volume assessment between proximal flow convergence and volumetric methods in patients with significant primary mitral regurgitation [PDF]
European Heart Journal - Cardiovascular Imaging, 2022 Abstract Funding Acknowledgements Type of funding sources: None. Background. Discrepancies have been observed between transthoracic echocardiography (TTE) and cardiac magnetic resonance imaging (MRI) severity grading in primary mitral regurgitation (MR). Purpose. To

The impact of different geometric assumption of mitral annulus on the assessment of mitral regurgitation volume by Doppler method [PDF]
Cardiovascular Ultrasound, 2019 Abstract Background Mitral regurgitation volume (MRvol) by quantitative pulsed Doppler (QPD) method previously recommended suffers from geometric assumption error because of circular geometric assumption of mitral annulus (MA).

Fast Measurements of Flow Through Mitral Regurgitant Orifices With Magnetic Resonance Phase Velocity Mapping [PDF]
, 2004 Magnetic-resonance (MR) phase velocity mapping (PVM) shows promise in measuring the mitral regurgitant volume. However, in its conventional nonsegmented form, MR-PVM is slow and impractical for clinical use.

Towards comprehensive assessment of mitral regurgitation using cardiovascular magnetic resonance
Journal of Cardiovascular Magnetic Resonance, 2008 Cardiovascular magnetic resonance (CMR) is increasingly used to assess patients with mitral regurgitation. Its advantages include quantitative determination of ventricular volumes and function and the mitral regurgitant fraction, and in ischemic mitral ...
