- Abstract
Ischemic mitral regurgitation (IMR) is generally perceived as a disease with a normal mitral valve (MV) and a regurgitation based on left ventricular and annular changes, overlooking the importance of MV size and remodeling, which should be considered as one of the most important variables. The adaptive mechanism of the MV components following the onset of IMR is focused on the increase of chordae tendinae length and leaflets area and length to prevent the development of significant IMR and is multifactorial. Mitral valve enlargement in chronic aortic regurgitation as a compensatory mechanism to prevent functional mitral regurgitation in the dilated left ventricle.
