Figure 1: — A. Kaplan-Meier survival analysis of patients with or without previous cardiac surgery (PCS) after acute type A aortic dissection repair. The raw 5- and 10-year survival were significantly lower in the PCS group (66% and 42%) compared to that in the no PCS group (80% and 66%) B. Cox proportional hazard regression of survival. The hazard ratio of PCS vs. no PCS was 1.3 (95% CI: 0.8, 2.1), p=0.33.
