==Overview==
==Overview==
Regurgitation means leaking from a valve that doesn't close all the way. It is caused by diseases that weaken or damage the valve or its supporting structures. Mitral regurgitation becomes chronic when the condition persists rather than occurring for only a short time period. The causes of chronic mitral regurgitation should be distinguished from the acute mitral regurgitation causes.
The causes of mitral regurgitation (MR) depend on the acuity of the valvular abnormality and the underlying pathological mechanism. Acute MR occurs when there is sudden disruption of one or more of the components of the mitral valve, such as leaflet perforation, rupture of a chordae tendineae, or rupture of the papillary muscle. The sudden disruption of the mitral valve can be caused by [[infective endocarditis]], degenerative mitral valve disease, or acute [[ST elevation myocardial infarction]].<ref name="pmid24603192">{{cite journal| author=Nishimura RA, Otto CM, Bonow RO, Carabello BA, Erwin JP, Guyton RA et al.| title=2014 AHA/ACC guideline for the management of patients with valvular heart disease: executive summary: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines. | journal=J Am Coll Cardiol | year= 2014 | volume= 63 | issue= 22 | pages= 2438-88 | pmid=24603192 | doi=10.1016/j.jacc.2014.02.537 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=24603192  }} </ref>  Chronic primary MR is most commonly caused by [[mitral valve prolapse]]; other causes include [[rheumatic fever]] and [[Marfan's syndrome]].  Chronic secondary MR results from the dysfunction and dilatation of the left ventricle rather than an intrinsic abnormality in one of the components of the mitral valve and it can be caused by coronary artery disease (ischemic) or any disease causing [[left ventricular dysfunction]] and dilatation (functional).<ref name="pmid21586426">{{cite journal| author=Ciarka A, Van de Veire N| title=Secondary mitral regurgitation: pathophysiology, diagnosis, and treatment. | journal=Heart | year= 2011 | volume= 97 | issue= 12 | pages= 1012-23 | pmid=21586426 | doi=10.1136/hrt.2010.219170 | pmc= | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21586426  }} </ref>

'''Common Causes of Mitral Regurgitation'''
====Chronic Mitral Regurgitation====
=====Primary Mitral Regurgitation=====


*Acute Mitral Regurgitation.
*'''Developed World:''' [[Mitral valve prolapse]] ([[MVP]])
:*Dysfunction or injury to the mitral valve following a heart attack. [[Papillary muscle rupture]] or dysfunction that is associated with [[ST elevation myocardial infarction]].
*'''Developing World:''' [[Rheumatic heart disease]]
:*Infection of the heart valve (infective endocarditis). These conditions may rupture the valve or surrounding structures, leaving an opening for blood to move backwards.
:*Trauma.


*Chronic Mitral Regurgitation.
=====Secondary Mitral Regurgitation=====
:*[[Mitral valve prolapse]] now accounts for 45% of cases in the Western world.
* [[Ischemic heart disease]]
:*[[Ischemic heart disease]] / [[Coronary artery disease]].
* Dilated [[left ventricle]] (due to any cause of [[dilated cardiomyopathy]], including [[aortic insufficiency]], nonischemic dilated [[cardiomyopathy]] and [[noncompaction cardiomyopathy]])
:*[[Rheumatic heart disease]], in the past, this was the most common cause of MR in the Western world. In developing countries, [[rheumatic heart disease]] remains the most common cause.

Overview

The causes of mitral regurgitation (MR) depend on the acuity of the valvular abnormality and the underlying pathological mechanism. Acute MR occurs when there is sudden disruption of one or more of the components of the mitral valve, such as leaflet perforation, rupture of a chordae tendineae, or rupture of the papillary muscle. The sudden disruption of the mitral valve can be caused by infective endocarditis, degenerative mitral valve disease, or acute ST elevation myocardial infarction.[1] Chronic primary MR is most commonly caused by mitral valve prolapse; other causes include rheumatic fever and Marfan's syndrome. Chronic secondary MR results from the dysfunction and dilatation of the left ventricle rather than an intrinsic abnormality in one of the components of the mitral valve and it can be caused by coronary artery disease (ischemic) or any disease causing left ventricular dysfunction and dilatation (functional).[2]

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.[3][4]
