Quantitative assessment of mitral regurgitation: how best to do it

, 2012
Decisions 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 ...

Novel 3-dimensional effective regurgitation orifice area quantification serves as a reliable tool to identify severe mitral valve regurgitation

Scientific Reports
AbstractA precise quantification of mitral regurgitation (MR) severity is essential for treatment and outcome of patients with MR. 3D echocardiography facilitates estimation of MR but selection of patients with necessity of invasive treatment remains challenging.

Comprehensive assessment of the severity and mechanism of aortic regurgitation using multidetector CT and MR.

, 2010
Recent studies have suggested that both cardiac magnetic resonance (MR) and multidetector computed tomography (MDCT) can quantify aortic regurgitation (AR) by planimetry of the anatomical regurgitant orifice (ARO).

Dapagliflozin effect on functional mitral regurgitation and myocardial remodelling: The DEFORM trial

ESC Heart Failure
Aims Functional mitral regurgitation (FMR) is associated with adverse outcomes in patients with heart failure, and current guideline‐directed medical therapy (GDMT) offers limited efficacy in managing FMR.

Invasive Validation of Right Ventricular Stroke Volume and Tricuspid Regurgitant Volume Obtained from Three-Dimensional Echocardiography

Background: Quantifying tricuspid regurgitation (TR) severity by conventional Doppler echocardiography is challenging. Objectives: We sought to validate right ventricular (RV) stroke volumes (SV3DE) and tricuspid regurgitant volumes (RegVol3DE) measured ...

Paradox of disproportionate atrial functional mitral regurgitation and survival after transcatheter edge‐to‐edge repair

ESC Heart Failure
Aims This study aims to assess the applicability of the mitral regurgitation (MR) proportionality concept in patients with atrial functional mitral regurgitation (aFMR) treated with transcatheter edge‐to‐edge repair (M‐TEER).
