'''Mitral regurgitation''' ('''MR'''), '''mitral insufficiency''' or '''mitral incompetence''' is  a disorder of the [[heart]] in which  the [[mitral valve]] does not close properly when the heart pumps out [[blood]].  It is the abnormal leaking of blood from the [[left ventricle]],  through the mitral valve,  and into the [[left atrium]], when the left ventricle contracts, i.e. there is [[Regurgitation (circulation)|regurgitation]] of blood back into the left atrium.<ref>[http://www.mountsinai.org/Other/Diseases/Mitral%20valve%20regurgitation Mitral valve regurgitation] at [[Mount Sinai Hospital, New York|Mount Sinai Hospital]]</ref>  MR is the most common form of [[valvular heart disease]].<ref name='MedlineMitChron2008'>{{cite encyclopedia |last=Weinrauch |first=LA |author= |authorlink= |coauthors= |editor= |encyclopedia=Medline Plus Encyclopedia |title=Mitral regurgitation - chronic |url=http://www.nlm.nih.gov/medlineplus/ency/article/000176.htm |accessdate=2009-12-04 |edition= |date=2008-05-12 |year= |publisher=U.S. National Library of Medicine and National Institutes of Health |volume= |location= |id= |doi= |pages= |quote= }}</ref>
