Causes of Mitral regurgitation Ø Ø Ø Ø Ø Ø Annulus Calcification Endocarditis (abcess) Valvular-leaflets Myxomatous MV Disease Rheumatic Endocarditis Congenital-clefts Chordae Fused/inflammatory Torn/trauma Degenerative Endocarditis Papillary Muscles CAD (Ischemia, Infarction, Rupture) HCM Infiltrative disorders LV dilatation & functional regurgitation Trauma N Engl J Med 2001;345:740
Mitral regurgitation primary MR abnormalities of one or more of the components of the mitral valve cause it to leak LV volume overload LV remodeling myocardial dysfunction heart failure secondary MR mitral valve is usually normal LV damaged (MI, CAD, DCM) papillary muscle displacement and annular dilatation causing the mitral valve to leak
the presence of MR in ischemic and dilated cardiomyopathies worsens prognosis Ø interpretations (potentially very different): the volume overload created by the MR adds a greater pathologic? burden to an already adverse condition. the poorer ventricular function is the cause of the poorer prognosis and that the MR simply is an indicator of the poorer LV function. Ø the issue is central to the therapy for the condition. If secondary MR is a cause for worsened prognosis, it should represent a reasonable target for therapy. if secondary MR is simply a byproduct of disturbed LV geometry and function, correction of secondary MR may have little impact on outcome.

Take home message Ø clinical management focuses on treatment of the causal disease process, rather than on direct attempts to decrease regurgitant severity Ø more options for intervention available: medical therapy percutaneous intervention surgical valve repair or replacement Ø all must be considered!!! Ø a patient-centered approach to decision making Ø review of each case by a heart team: a nonprocedural valve-disease specialist an interventional cardiologist cardiologist a cardiac surgeon N Engl J Med 2011; 364:1462-1463
