Indirect quantification of mitral regurgitation using cardiovascular magnetic resonance: A comparison of techniques

DEPARTMENT of CARDIOVASCULAR SURGERY Quantification of Mitral Valve Regurgitation by Left Ventricular Volume and Flow Measurements Using Electron Beam Computed Tomography: Comparison with Magnetic Resonance Imaging

Method Forty-three patients, among them 33 with known mitral regurgitation, underwent electron beam CT and MR imaging. Total left ventricular stroke volume (TSV), antegrade stroke volume (ASV), and mitral regurgitation volume (MRV) and fraction (MRF) were determined and compared between the two modalities. Additionaly electron beam CT measurements were compared with the corresponding echocardio...

Characterization and quantification of dynamic eccentric regurgitation of the left atrioventricular valve after atrioventricular septal defect correction with 4D Flow cardiovascular magnetic resonance and retrospective valve tracking

BACKGROUND To characterize and directly quantify regurgitant jets of left atrioventricular valve (LAVV) in patients with corrected atrioventricular septal defect (AVSD) by four-dimensional (4D)Flow Cardiovascular Magnetic Resonance (CMR), streamline visualization and retrospective valve tracking. METHODS Medical ethical committee approval and informed consent from all patients or their parent...

Quantitative Assessment of Mitral Regurgitation: Comparison Between Three-dimensional Transesophageal Echocardiography and Magnetic Resonance Imaging Running Title: Shanks et al: Mitral regurgitation quantification: 3D TEE vs. MRI

Quantitative assessment of mitral regurgitation: comparison between three-dimensional transesophageal echocardiography and magnetic resonance imaging.

BACKGROUND quantification of mitral regurgitation severity with 2-dimensional (2D) imaging techniques remains challenging. The present study compared the accuracy of 2D transesophageal echocardiography (TEE) and 3-dimensional (3D) TEE for quantification of mitral regurgitation, using MRI as the reference method. METHODS AND RESULTS two-dimensional and 3D TEE and cardiac MRI were performed in ...
