Fig 1 (A) Kaplan-Meier curves and confidence intervals (shaded areas) for each of the three surgical techniques: David (blue line); mechanical Bentall (red line); and bioprosthetic Bentall (green line). (B) The 10-year Kaplan-Meier survival was 98% (95% confidence interval: 84% to 99%) for the David group (red line); and 57% (95% confidence interval: 42% to 70%) for the Bentall group (blue line).

Fig 2 Multivariable survival analysis after controlling for age, sex, history of renal failure, chronic obstructive pulmonary disease, and cardiogenic shock showed reduced late survival for bioprosthetic Bentall (blue line) and mechanical Bentall (red line) subsets as compared with David (green line) group (adjusted hazard ratio 13, 95% confidence interval: 1.5 to 105, p = 0.02; adjusted hazard ratio 10, 95% confidence interval: 1.0 to 101, p = 0.05, respectively). Shaded areas indicate confidence intervals. The Annals of Thoracic Surgery , DOI: ( /j.athoracsur ) Copyright © 2018 The Society of Thoracic Surgeons Terms and Conditions
