    Abstract:
    BACKGROUND: The aim of this study was to compare the outcomes of a primary and secondary Bentall-De Bono procedure. METHODS: From 2008 to 2015 (8-year period), 308 patients underwent a Bentall-De Bono procedure in our institute. The mean age was 43 ± 13 years and 80% were men. Twenty-eight patients had prior cardiac surgery through a median sternotomy (group 1) and 280 underwent a primary Bentall-De Bono procedure (group 2). Various preoperative and perioperative parameters were analyzed before and after propensity-score matching. RESULTS: Before propensity-score matching, patients undergoing a secondary Bentall-De Bono procedure had a worse preoperative profile, as indicated by a higher EuroSCORE II ( p < 0.0001), with hospital mortality in group 1 of 14% (4/28) and 5% (14/280) in group 2 ( p = 0.069). After propensity-score matching, there was no significant difference in EuroSCORE II ( p = 0.922) or hospital mortality ( p = 0.729). After adjusting for the different variables, repeat sternotomy could not be identified as an independent predictor of postoperative mortality or morbidity. Survival at the end of 1 and 5 years in both groups showed no significant differences before or after propensity-score matching ( p = 0.328 and p = 0.356, respectively). In Cox multivariable regression analysis, reoperation was not identified as an independent factor for survival before ( p = 0.559) or after propensity-score matching ( p = 0.365). CONCLUSION: A secondary Bentall-De Bono procedure can be performed with acceptable mortality and morbidity, and with midterm survival rates comparable to those of a primary Bentall-De Bono procedure.
