Total anomalous pulmonary venous connection (TAPVC) is a complex congenital heart disease, requiring surgical repair. Pulmonary venous obstruction (PVO) is the major complication, with limited effective reinterventions and poor outcomes. This trial aims at investigating that postoperative anticoagulant management reduce the incidence of PVO.


Total anomalous pulmonary venous connection (TAPVC) is a complex congenital heart disease, with all the pulmonary veins connecting to the right heart system through collateral vessels, accounts for about 3% of congenital heart disease. Pulmonary venous obstruction (PVO) is a major complication, with limited effective reinterventions and poor outcomes. The major challenge for surgical repair of TAPVC is to lower the incidence of PVO.

Previous studies in our center showed the abnormal coagulation function, such as elevated International Normalized Ratio (INR), and decreasing of prothrombin activity, are associated with a higher rate of PVO. Some researches suggested that postoperative application of anticoagulants might reduce the incidence of PVO, however, the evidences are still limited. This trial will randomize patients to receive either conventional postoperative management or continuous infusion anticoagulant (Heparin) until the removal of deep vein catheter. The primary endpoint will be incidence of PVO, days of chest drainage more than 40ml/d, and mortality rate. Secondary endpoints including readmission, functional capacity assessment, quality of life and incidence of complications will also be collected.
