Total anomalous pulmonary venous connection (TAPVC) is a relatively rare but complex congenital heart disease characterized by the anomalous drainage of the pulmonary veins. Rather than connecting to the left atrium, the pulmonary veins drain either directly or indirectly into the systemic venous circulation or the right atrium via abnormal pathways. While there is broad consensus on the diagnostic criteria for TAPVC, significant debate persists regarding the optimal timing of surgical intervention, preferred surgical techniques, and postoperative management including re-intervention strategies. This article formulates a Chinese consensus based on evidence-based data from the literature and opinions from domestic experts, with the goal of further standardizing the surgical treatment of TAPVC in China.
