OBJECTIVES: To assess the early and mid-term outcomes and related predictors in a consecutive series of patients who underwent surgical ventricular restoration (SVR) combined with additional mitral valve (MV) repair. METHODS: From January 2001 to October 2014, 626 patients underwent SVR; of these, 175 (28%, median age 65) had an additional MV repair. Anterior, inferior or diffuse remodelling was present in 124 (71%), 41 (23%) and 10 (6%) patients, respectively. The median ejection fraction was 30%, whereas mitral regurgitation grade was 3.3 ± 0.8. Multivariable logistic regression and Cox regression analyses were used to identify predictors of early and mid-term mortality. RESULTS: Operative death occurred in 25 patients (14.3%). Independent predictors of early mortality were age, creatinine and ejection fraction score [odds ratio (OR) = 5.1, 95% confidence interval (CI) 2.5-10.3], previous stroke (OR = 8.0, 95% CI 1.5-44), unstable angina (OR = 8.8, 95% CI 1.5-53) and diffuse remodelling (OR = 5.8, 95% CI 1.02-33). Average follow-up was 42 ± 37 months. The actuarial survival rate of the whole patient population at 3, 5 and 8 years was 72 ± 4, 65 ± 4 and 45 ± 6%, respectively. Risk factors for late mortality were preoperative creatinine (OR = 2.6, 95% CI 1.5-4.4), previous implantation of cardioverter defibrillator (OR = 4.7, 95% CI 1.6-5.8), whereas the absence of angina at the time of surgery emerged as protective factor (OR = 0.46, 95% CI 0.23-0.89). CONCLUSIONS: MV repair combined with SVR is a complex and challenging procedure that can be performed with acceptable early and mid-term results. Interestingly, angina features predict both early and late outcome, with unstable angina at the time of surgery being a predictor of poor early outcome and the absence of angina at surgery, a predictor of favourable outcome at mid-term follow-up.
