PY - 2017 T2 - Cardiac Surgery in the Adult, 5e AB - Functional mitral regurgitation (FMR) is a complication of ischemic or dilated cardiomyopathy, occurring secondary to left ventricular (LV) geometrical distortion from tenting, inferobasilar migration, apical displacement, annular dilation and posterior leaflet restriction, and/or regional LV wall dysfunction. MR leads to a vicious cycle of LV volume overload, increased geometric distortion and progressive MR. FMR complicating congestive heart failure predicts a poor survival. Mitral surgery, to treat FMR has been undertaken with an acceptably low operative mortality. However, the exact MR surgery (repair or replacement) for which patient and what benefit, remains controversial.
