Abstract
OBJECTIVE This study aimed to investigate the association between long-term survival and different management of major aortopulmonary collateral arteries in patients with pulmonary atresia, ventricular septal defect, and major aortopulmonary collateral arteries. METHODS From November, 2009 to October, 2018, a total of 98 consecutive patients with pulmonary atresia, ventricular septal defect, major aortopulmonary collateral arteries, and hypoplastic pulmonary arteries treated with modified Blalock-Taussig shunt or right ventricle-pulmonary artery connection were included. Fifty-five patients who received occlusion or ligation of major aortopulmonary collateral arteries during or after palliative procedure were occlusion group, and the other 43 patients were no occlusion group. The early and late outcomes were compared. RESULTS The mean duration of follow-up was 30.9 months in no occlusion group and 49.8 months in the occlusion group (p < 0.001). Multivariate analysis showed that only no occlusion of major aortopulmonary collateral arteries was predictive of total mortality (Hazard Ratio: 4.42, 95% CI: 1.27 to 15.42, p = 0.02). The Kaplan-Meier survival curves confirmed that patients without occlusion of major aortopulmonary collateral arteries demonstrated worse survival as compared with the occlusion group (p = 0.013). The Kaplan-Meier survival curves of patients who underwent different palliative procedures showed no differences. CONCLUSIONS For patients with pulmonary atresia, ventricular septal defect and major aortopulmonary collateral arteries when a primary repair is not feasible, those without occlusion of major aortopulmonary collateral arteries have a higher risk of death following an initial palliative procedure compared with patients who underwent occlusion of major aortopulmonary collateral arteries. The occlusion of major aortopulmonary collateral arteries is not associated with a higher rate of complete repair or better improvement of pulmonary artery growth.

Abstract
OBJECTIVES The objective of this study was to compare our clinical outcomes of the central shunt and the right ventricle-pulmonary artery (RV-PA) connection in patients with pulmonary atresia, ventricular septal defect and the major aortopulmonary collateral arteries. METHODS From November 2009 to October 2017, a total of 157 consecutive patients with pulmonary atresia, ventricular septal defect, the major aortopulmonary collateral arteries and the hypoplastic PAs who underwent palliative surgery were included. Seventy patients underwent the central shunt (the central shunt group) and 87 patients underwent the RV-PA connection (the RV-PA group). Propensity score matching was used to create 2 cohorts with similar baseline characteristics: 56 central shunt patients were one-to-one-matched with 56 RV-PA connection patients. The early and late outcomes were compared. RESULTS The median duration of follow-up was 18 months in the central shunt group and 22 months in the RV-PA group (P = 0.10). The probability of complete repair was significantly lower in the central shunt group as compared with the RV-PA group (P = 0.048). The Kaplan-Meier estimates of complete repair rates were 47.2 ± 10.0% after 3 years and 56.0 ± 11.6% after 5 years in the central shunt group, which were lower as compared with 62.3 ± 7.6% after 3 years and 74.5 ± 7.2% after 5 years in the RV-PA group. The increase in the mean McGoon ratio and the mean Nakata index were significantly lower in the central shunt group than those in the RV-PA group (0.57 ± 0.52 vs 1.02 ± 0.44, P = 0.036; 98.2 ± 35.1 mm2/m2 vs 176.9 ± 85.4 mm2/m2, P = 0.025, respectively). The in-hospital morbidity and mortality after complete repair were similar between 2 groups. CONCLUSIONS Compared with the central shunt, the RV-PA connection appears to be a more effective palliative procedure to improve the probability of complete repair and PA growth in patients with pulmonary atresia, ventricular septal defect and the major aortopulmonary collateral arteries, in whom primary repair is not feasible.
