Quantitative assessment of mitral regurgitation comparison between three-dimensional Transesophageal Echocardiography and Magnetic Resonance Imaging

, 2010
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 ...

Aortic stiffness: an old concept for new insights into the pathophysiology of functional mitral regurgitation.

, 2013
Functional mitral regurgitation (FMR) is thought to be linked with ventricular afterload. However, the relation between aortic stiffness, which is a main determinant of ventricular afterload, and quantitatively assessed mitral regurgitation is unknown. A

Understanding continuous-wave Doppler signal intensity as a measure of regurgitant severity

, 1997
Continuous-wave Doppler signal intensity is commonly expected to reflect the severity of mitral regurgitation. Physical principles predict that alignment of the imaging beam, flow velocity, and turbulence can also be important or even dominant ...

Simulation of chronic mitral regurgitation

, 1995
In mitral regurgitation the left ventricle enlarges in order to increase its stroke volume because of the regurgitation through the mitral valve. The amount of this volume increase, and of the consequent increase in left ventricular mass, its dependent ...

Mitral Regurgitation After Myocardial Infarction: A Review

, 2006
Mitral regurgitation after myocardial infarction is the result of multifactorial processes involving local and global left ventricular remodeling. The prevalence of mitral regurgitation varies from 11% to 59%.

Transcatheter edge-to-edge repair for ventricular secondary mitral regurgitation: perfect synergy with optimal medical therapy

REC: Interventional Cardiology (English Ed.)
Secondary ventricular mitral regurgitation (MR) is a common valvular disorder resulting from ventricular dilation or dysfunction rather than primary leaflet abnormalities.1 Progressive left ventricular (LV) dilation and spherical reshaping displace the ...

Effect of losartan on excercise tolerance and echocardiographic parameters in patients with mitral regurgitation

, 2008
Objectives. The aim of this study was to assess the effects of losartan treatment on exercise tolerance and echocardiographic parameters in patients with mitral regurgitation (MR) secondary to mitral valve prolapse or rheumatic heart disease.

Quantification of regurgitant fraction in mitral regurgitation by cardiovascular magnetic resonance: comparison of techniques.

, 2016
BACKGROUND AND AIM OF THE STUDY: Cardiovascular magnetic resonance (CMR) assessment of mitral regurgitant volume from the subtraction of the right ventricular stroke volume (RVSV) from left ventricular stroke volume (LVSV) has commonly been performed ...

The role of 3D transesophageal echocardiography during percutaneous closure of paravalvular mitral regurgitation

, 2009
PARAVALVULAR MITRAL REGURGITATION (MR) after mitral valve replacement may lead to heart failure and hemolysis. There are data to suggest that closure of paravalvular mitral regurgitant leaks confers an improved prognosis, with reduced hemolysis and ...
