The percentage incidence of each anatomic subtype is plotted as a function of age at repair. In the neonatal period (<1 month), the majority of cases are intracardiac. As age at repair increases, the percentage of supracardiac lesions increases. (Least squares multiple regression used to smooth data).

5. Fig 4
Survival stratified by age at first operation. Early deaths are the major determinant of age-based differences in survival (p < 0.01).

6. Fig 5
Cumulative operative mortality for 125 consecutive cases with simple anatomy. A least squares regression line is included with a marker at the 50th case in the series, corresponding to an operative date of September 5, Operative mortality for the first 50 cases was 26.0% and for the following 76 cases was 7.9%.

7. Fig 6
Cumulative operative mortality for 44 consecutive cases with complex anatomy. A linear regression is plotted to demonstrate the lack of change in operative mortality.
