Common Causes of Mitral Regurgitation
Chronic Mitral Regurgitation
- Developed World: Mitral valve prolapse (MVP).[1]
- 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.[2]
- Marfan's syndrome [3]
Acute Mitral Regurgitation
- Acute bacterial endocarditis. The predominant organism is S. aureus, but varies depending upon the patient.[3]
- Papillary muscle rupture or dysfunction,[3] associated with ST elevation myocardial infarction
