Summary § Functional mitral regurgitation • Historically early treatment of MR improves outcomes • Medical therapy can reverse remodel heart and decrease MR • Surgical treatment • Replacement high early mortality • Repair high rates of recurrent MR • Percutaneous • Repair Technologies • Lower early morbidity and mortality • Appears to have survival benefit vs. Medical tx • Replacement • Early experience mixed with respect to mortality § Early Treatment that reduces MR with acceptable Morbidity and Mortality
