known as primary MR (or “organic” MR), or due to dilation of the mitral valve annulus associated with impaired left ventricular function, known as secondary MR (or “functional” MR).

The consequences of ventricular dilation include dilation of the mitral annulus, apical and lateral displacement of the papillary muscles with tethering of the subvalvular apparatus and mitral ...

Functional mitral valve regurgitation occurs when the left atrium or left ventricle dilates, causing the mitral valve annulus to also dilate and prevent the mitral valve leaflets from properly ...

where a normal valve regurgitates because of ventricular dysfunction and mitral annular dilatation. For a long time, rheumatic fever was the predominant cause of organic MR. Now the main causes ...

Background Although the prognostic implications of severe mitral regurgitation (MR) are well recognised, they are less clear ...

It is for use in the mitral or tricuspid position ... band adapts to three-dimensional contour of the annulus while providing support against dilation. Polyester velour cloth band encourages ...
