    Abstract:
    OBJECTIVES: This study aimed to review surgical experiences in patients with infracardiac total anomalous pulmonary venous connection (TAPVC). METHODS: This retrospective study included 63 infants who underwent conventional repair (n = 27) and sutureless repair (n = 36) from 1 February 2009 to 31 June 2019. Kaplan-Meier curves and Cox regressions were applied to analyse the overall survival and risk factors. Cumulative incidence curves and competing risk models were used to evaluate postoperative pulmonary venous obstruction (PVO). RESULTS: There were 4 hospital deaths and 2 late deaths, and 8 patients experienced postoperative PVO. The survival rates at 30 days, 1 year and 5 years were 95.2%, 90.5% and 90.5%, respectively. The overall survival rate was significantly higher in the sutureless group than that in the conventional group. The cumulative incidence of postoperative PVO in the conventional group was higher than that in the sutureless group. Univariable Cox regression analyses showed that lower surgical weight, increase in preoperative international normalized ratio, prolonged cardiopulmonary bypass time and aortic cross-clamp time and longer duration of postoperative ventilation were associated with higher mortality. Longer cardiopulmonary bypass time, lower preoperative prothrombin activity and the increasing preoperative international normalized ratio before surgical repair were associated with a higher incidence of postoperative PVO. CONCLUSIONS: Both sutureless and conventional repairs for patients with infracardiac TAPVC achieved favourable postoperative outcomes. There was no death in the sutureless repair group. Compared to conventional repair, sutureless repair was associated with lower mortality and lower incidence of restenosis in pulmonary veins and anastomosis.
