Figure 1 Actuarial survivals after Norwood palliation for standard-risk and high-risk patients from September 2000 to September 2008. Operative survival and survival to cavopulmonary anastomosis are comparable between groups; 1-year survival and survival to date are lower among high-risk patients than among standard-risk patients (P = .01 and P = .001, respectively).
