BACKGROUNDS: Outcomes of mitral valve repair have been well described for @entity1 with @entity179 . The hemodynamic effects of repair have not been as well studied, however. We report hemodynamic outcomes in these @entity1 . METHODS: We reviewed 1147 @entity1 who underwent isolated mitral valve repair for degenerative mitral @entity338 between January 2004 and December 2013. Baseline characteristics included mean age 58.6      13.4  years, male sex in 792 @entity1 (69.1%), mean ejection fraction of 0.64      0.07, and New York Heart Association class III/IV @entity1353 in 215 @entity1 (18.8%). RESULTS: Mitral valve repair involved the posterior leaflet in 764 @entity1 (66.6%), anterior leaflet in 57 @entity1 (5.0%), both leaflets in 260 @entity1 (22.7%), and annuloplasty alone in 66 @entity1 (5.8%). Among the @entity1 who underwent posterior leaflet repair, 713 (93.3%) were treated with our standard technique of triangular leaflet resection/plication and repair with partial posterior band annuloplasty using an unmeasured 63-mm flexible band. Follow-up echocardiography data were obtained in 1138 survivors (99.4%) at 600      880  days. Mild or less @entity338 was present at last follow-up in 1030 @entity1 (90.5%). The mean mitral valve gradient was 3.1      1.4  mm Hg in the operating room and 3.5      1.6  mm Hg at the last follow-up (P  <  .001). The mean mitral valve gradient decreased from the first to the second median time periods (124.5  days) of follow-up (3.7      1.6  mm Hg to 3.3      1.8  mm Hg; P  <  .001). CONCLUSIONS: Mitral valve repair for @entity179 results in a small mitral valve gradient that appears to decrease with time after discharge.
