Complications
Occurs as the result of left atrial enlargement.
Treated with rate control and proper anticoagulation.
Occurs as the result of left-sided failure and pressure overload.
Mitral valve repair or replacement is the only treatment.
May be caused by manipulation of the ascending aorta.
May result from pannus formation or degenerative disease.
There is an increase in left ventricular (LV) end-diastolic volume as a compensatory mechanism in early stages; however, as time progresses LV dysfunction occurs, accompanied by impaired ejection and increased end-systolic volume.
With time there may be further LV dilation and increased LV filling pressure. Eventually this leads to reduced forward flow and increased LV filling pressure.
Mitral valve repair or replacement is the only treatment.[32]
1% per year may require reoperation.
Recurrent MR may occur as a result of progressive degenerative disease, lack of use of an annuloplasty ring, the use of chordal shortening instead of artificial chordae or transposition, and lack of use of a sliding plasty for posterior annulus dilation.
May be related to surgical procedure, endocarditis, or acute myocardial infarction.
Both early and late. Usually caused by Staphylococcus within days of the operation.
