4. Figure 3
Kaplan-Meier survival analysis after birth in patients with right ventricle–to–pulmonary artery conduit (RVPAC) or modified Blalock-Taussig shunt (mBTS). (A) 120-day survival. Survival with RVPAC is significantly better (p < 0.01) than with mBTS. (B) 1-year survival. Difference is not significant.

5. Figure 4
Estimated cumulative hazard during the interstage period for patients with right ventricle–to–pulmonary artery conduit (RVPAC) and modified Blalock-Taussig shunt (mBTS). Graphs represent the relation between age and mortality during the interstage period. Patients with early death after stage 1 palliation were excluded.

6. Figure 5
Kaplan-Meier interstage survival analysis with confidence intervals in patients with right ventricle–to–pulmonary artery conduit. Graphs represent survival from birth until death during the interstage period. Patients with early death after stage 1 palliation were excluded. Survival is expressed as a proportion with 95% confidence intervals. Probability of survival to an age of 124 days was 94% ± 6% in the interstage period (95% confidence interval, 83 to 100).

Timeline and circumstances of interstage death. Cardiac diagnoses are underlined. (HLHS = hypoplastic left heart syndrome; ISD = interstage death; mBTS = modified Blalock-Taussig shunt; RVPAC = right ventricle–to–pulmonary artery conduit.)

Cardiac catheterization and interventions before stage 2 palliation. Differences were not significant. (mBTS = modified Blalock-Taussig shunt; RVPAC = right ventricle–to–pulmonary artery conduit.)
