OBJECTIVES: Surgical management of the aortic root in type A acute aortic dissection (TAAAD) is controversial. This study compares short- and long-term outcomes of root replacement (RR) versus conservative root management (CR).
METHODS: Between 1999 and 2014, 296 patients with TAAAD were treated in our department. The mean age was 63.7 years. Of the total, 69% were male. Ten patients (3%) presented with Marfan syndrome or bicuspid aortic valve. RR was performed in 119 (40%) patients, whereas CR in 177 (60%). Pre- and intraoperative data were stratified according to root management, and treatment bias was addressed by propensity-score (PS) analysis. Independent predictors of hospital and long-term mortality and proximal aortic reoperation were identified using multivariable logistic and Cox regression models.
RESULTS: Using PS analysis, we obtain two groups of 82 patients. The matched cohort hospital mortality rate was 21% in the CR group and 26% in the RR group (P = 0.45). The unadjusted comparison showed no statistical difference in early and long-term mortality between the groups. This result was confirmed after standard logistic regression and propensity-adjusted logistic regression. Freedom from proximal aortic reintervention was higher in the RR group (at 7 years RR: 96 ± 3% vs CR: 80 ± 6%, log-rank P = 0.02) and remained high in the matched cohort of patients (at 7 years RR: 98 ± 2 vs CR: 86 ± 6, log-rank P = 0.06).
CONCLUSIONS: Conservative and aggressive root management in acute aortic dissection provided similar results for early and late mortality. Nevertheless, a more extensive root intervention appeared to be protective against aortic reintervention.
