Fig 1 Intervention and outcomes schema for total anomalous pulmonary venous connection (TAPVC). The clinical course of each patient is stratified according to variables that significantly influenced survival; two ventricles versus one ventricle, obstructed versus unobstructed pulmonary veins, and type of repair. aDenotes 1 patient missing from subsequent analysis as there was no record of the type of repair performed; the patient had single-ventricle anatomy with unobstructed TAPVC and a complex, elective repair, and suffered early mortality.

Fig 2 Kaplan-Meier estimated survival in total anomalous pulmonary venous connection for the entire cohort of 123 patients. For the entire cohort, Kaplan-Meier estimated 1-month survival is 85% (95% confidence interval [CI], 80% to 90%), 1-year survival is 75% (95% CI, 68% to 83%) and 3-year survival is 73% (95% CI, 66% to 80%). The error bar represents the 95% CI. The Annals of Thoracic Surgery 2005 79, 596-606DOI: (10.1016/j.athoracsur.2004.07.005) Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions
Fig 3 Kaplan-Meier survival in total anomalous pulmonary venous connection for single-ventricle versus two-ventricle patients. For two-ventricle patients (solid circle), the estimated 1-month survival is 95% (95% confidence interval [CI], 90% to 100%), 1-year survival is 89% (95% CI, 84% to 94%) and 3-year survival is 86% (95% CI, 81% to 92%). For one-ventricle patients (open circle), the estimated 1-month survival is 65% (95% CI, 53% to 77%) and 1- and 3-year estimated survival is 47% (95% CI, 35% to 59%). Survival time was significantly shorter in single-ventricle patients (p < 0.0001, log-rank test = 19.68). Error bar represents 95% CI.

Fig 4 Kaplan-Meier survival in total anomalous pulmonary venous connection for patients with a single ventricle in the presence (open circle) or absence (solid circle) of prerepair pulmonary venous obstruction. Survival in single-ventricle patients was significantly compromised in patients with prerepair pulmonary venous obstruction (p < 0.01, log-rank test = 5.69). Error bars for patients with obstruction represent a 95% confidence interval (CI) of 16% to 46%, and for patients without obstruction, a 95% CI of 54% to 82%.
