Objective To explore the clinical application of total cavopulmonary connection(TCPC) in treatment of some complex cardiac anomalies for ameliorating the curative effectiveness and survival rate.

Objective To introduce total extracardiac cavopulmonary connection in the treatment of complicated cyanosis congenital heart disease.

Surgical treatment of the complex congenital heart disease with the extracardiac conduct total cavopulmonary connection;

Objective: To evaluate the results of total cavopulmonary connection(TCPC) in the treatment of complex congenital heart diseases.

To establish a new model of total cavopulmonary connection (TCPC) by improving the vascular anastomosis between vena cava and pulmonary artery and to study the postoperative hemodynamic changes, a Y shaped prosthetic blood vessel was used, one limb of the prosthesic was anastomosed with vena cava, and the other to pulmonary artery in an end to side way.
