Background: Contemporary mitral valve repair aims at correction of leaflet function and stabilization of the annulus using closed or open annuloplasty rings. Aim of this study was to compare the outcome after OA versus CA mitral valve repair.

Methods: 933 patients who received mitral valve surgery between January 2005 and December 2014 were evaluated. Differences in baseline variables were adjusted using propensity score (PS) matching which included logistic regression with 41 preoperative covariates. Mitral valve pathology was degenerative 96.6% (OA) and 95.5% (CA).

Results: Cross-clamp time was 82 ± 30 minute (OA) versus 86 ± 32 minute (CA), p = ns. The repair rate was 99.1% in both groups. Postoperative intensive care unit stay was one day in both groups. In hospital mortality was 3.1% (OA) versus 2.3% (CA), p= ns. Postoperative none/trace or mild mitral incompetence at transthoracic echo was diagnosed in 96.9% (OA) versus 97.2% (CA), p = ns

Conclusion: Mitral valve surgery leads to good outcomes and a high repair rate using standard techniques including OA and CA. In case of potential future need for repeat intervention CA may provide a better landing zone.
