244/244 | Higher rate of MR recurrence in RMA | | Magne et al. [20] | 370 | 12 | MVRpl/RMA
184/185 | Similar rate of MR recurrence | | Micovic et al. [13] | 138 | 7 | MVRpl/RMA
52/86 | Better survival in RMA | | Milano et al. [14] | 522 | 12 | MVRpl/RMA
106/416 | Lower rate of 30-day mortality in RMA | | Silbermann et al. [15] | 52 | 3,2 | MVRpl/RMA
14/38 | Similar rate of survival. Better improvement in NYHA for RMA | | Thourani et al. [21] | 1250 | 10 | MVRpl/RMA
625/625 | Better 30 days and 10 yrs survival in RMA | | McGee et al. [18] | 585 | 5 | RMA | After 1 yrs 3+ or 4+ MV regurgitation increased () | | Yan et al. [12] | 36 | 1 | MVRpl-cp/MVRpl-pp
21/15 | Significant early advantage with MV
Sparing procedure | | Natsuaki et al. [16] | 28 | 30 days | MVRpl-cp/MVRpl-pp/RMA
15/13/15 | Significant early advantage with MV
Sparing procedure | | Rozich et al. [22] | 15 | 7/10 days | MVRpl-cp/MVRpl-pp
8/7 | MVRpl-cp smaller LV size and LV function | | David et al. [11] | 17 | 24 months | MVRpl-cp/MVRpl-pp/RMA
6/6/5 | Better improvement of LV function. Significant benefit in preservation of chordae attachment to leaflet and PMs |

LV: left ventricle; MR: mitral regurgitation; MVRpl: mitral valve replacement; MVRpl-cp: mitral valve replacement complete preservation; MVRpl-pp: partial preservation; PMs: papillary muscles; RMA: restrictive mitral annuloplasty; S-MVR: secondary mitral valve regurgitation surgery.
