2. Fig 1
Survival analysis for all patients up to 30 days after surgery by operation type. The numbers on the survival curves represent the number of patients at risk at various time points. There was no significant difference in survival functions among the three groups (log-rank test p = 0.41). (CAVSD = complete atrioventricular septal defect; TOF = tetralogy of Fallot.)

3. Fig 2
Survival analysis of all patients up to 30 days after surgery by the presence or absence of a double orifice atrioventricular valve (DOAVV). The numbers on the survival curves represent the number of patients at risk at various time points. The probability of survival among patients with a double orifice valve was significantly lower than among patients without the condition (log-rank test p < 0.001).

4. Fig 3
Survival analysis of all patients for the full follow-up period by the presence or absence of a double orifice atrioventricular valve (DOAVV). The numbers on the survival curves represent the number of patients at risk at various time points. There was a significant difference in survival functions between patients with a double orifice valve and patients without the condition (log-rank test p < 0.001). Patients with a double orifice valve had a lower probability of survival.

5. Fig 4
Analysis of the time to reoperation for all patients stratified by the type of repair. The numbers on the survival curves represent the number of patients at risk at various time points. There was no significant difference in survival functions among the three types of operation (log-rank test p = 0.49). (CAVSD = complete atrioventricular septal defect; TOF = tetralogy of Fallot.)

6. Fig 5
Analysis of the time to reoperation for all patients stratified by presence or absence of trisomy 21. The numbers on the survival curves represent the number of patients at risk at various time points. There was a significant difference in survival functions (p = 0.001) between the two groups and patients with trisomy 21 had a higher probability of survival (in terms of freedom from reoperation) than did chromosomally normal children.

7. Fig 6
Analysis of the time to reoperation for all patients by the presence or absence of dysplastic left atrioventricular valve (LAVV). The numbers on the survival curves represent the number of patients at risk at various time points. There was a significant difference in survival functions between the two groups (p < 0.001) and patients with a dysplastic LAVV had a lower probability of survival (in terms of freedom from reoperation).
