N2 - OBJECTIVES: The prognostic impact of failed mitral valve repair (FMR) on in-hospital outcome after redo mitral valve surgery has not been thoroughly investigated.METHODS: Hospital outcomes after redo mitral valve surgery because of an FMR in patients from nine European centres were reported. Logistic regressions identified predictors of mortality in combined or isolated redo mitral valve operations. Hospital outcome was compared between propensity-matched cohorts with FMR and native mitral valves in the context of redo surgery and FMR versus failed prostheses.RESULTS: A total of 246 patients with FMR yielded a 6.5% mortality rate at redo surgery. FMR per se did not impact mortality at multivariable analysis ( P = 0.64). A preoperative Global Initiative for Chronic Obstructive Lung Disease (GOLD) score ≥2 chronic obstructive lung disease (COPD) (OR 15.2, P < 0.01), left ventricular ejection fraction <30% (odds ratio (OR) 21.5, P = 0.005), major injury to cardiovascular structures at re-entry (OR 27.2, P < 0.01) or injury to patent left internal mammary artery-coronary artery bypass graft (OR 7.6, P = 0.03) predicted mortality in the whole FMR population. GOLD ≥ 2 COPD (OR 12.3, P = 0.049), age at surgery (OR 1.15 for each incremental year, P = 0.049) and cardiopulmonary bypass duration (OR 1.02, P = 0.022) predicted mortality in isolated redo mitral valve surgery for FMR. The fourth (> 68 years = 13.8% mortality) and the fifth quintiles of age (≥73.4 years = 14.8%) reported the highest mortality (OR 3.8 and 4.2 respectively, P = 0.002) in this subgroup. Propensity-matched cohorts of FMR and native mitral valves in the context of redo surgery showed no differences in terms of mortality ( P = 0.69) and major morbidity (acute myocardial infarction P = 0.31, stroke P = 0.65, acute kidney injury P  = 1.0), whereas more perioperative dialysis ( P = 0.04) and transfusions ( P = 0.02) were noted in propensity-matched failed prostheses compared to FMR.CONCLUSIONS: A failed mitral repair does not impact hospital outcome of redo surgery. Given the role of severe left ventricular dysfunction and advanced age on hospital mortality rates, an early indication for redo surgery may improve outcome.
