*'''Developing World:''' [[Rheumatic heart disease]]
* [[Ischemic heart disease]] causes mitral regurgitation by the combination of ischemic dysfunction of the [[papillary muscles]], the abnormal motion of the underlying wall, and the dilatation of the [[left ventricle]] that is present in ischemic heart disease, with the subsequent displacement of the papillary muscles and the dilatation of the [[mitral valve]] annulus.
*Secondary mitral regurgitation due to the dilatation of the [[left ventricle]], caused by stretching of the mitral valve annulus and displacement of the papillary muscles.  This dilatation of the left ventricle can be due to any cause of [[dilated cardiomyopathy]], including [[aortic insufficiency]], nonischemic dilated [[cardiomyopathy]] and [[Noncompaction Cardiomyopathy]]. It is also called '''functional mitral regurgitation''', because the papillary muscles, chordae, and valve leaflets are usually normal.<ref>[http://www.uptodate.com/patients/content/topic.do?topicKey=~Ux3kbGWsXmiaqiH Functional mitral regurgitation] By William H Gaasch, MD.
