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

Objective To summarize the experience of clinical application of extracardiac conduct total cavopulmonary connection in complex congenital heart disease. Methods Twelve patients with complex congenital heart disease underwent extracardiac conduct total cavopulmonary connection, including 7 cases of functional univentricle, 3 cases of complete atrioventricular septal defect with double outlet of right ventricle, 2 cases of double outlet of right ventricle with transposition of the great artery. Among them, 1 patient had cor triatriatum, 3 patients had left superior vena cave, 1 patient had severe mitral valve insufficiency. Results There was no early death or postoperative death. All patients were followed up from 2 to 48 months. All patients had no arrhythmias. The artrial oxygen saturation was from 0.93 to 0.97. The cardiac function was in NYHA classⅠ to Ⅱ. Conclusion Extracardiac conduct total cavopulmonary connection is a simple procedure. It can be used for complex congenital heart disease which can not be corrected in anatomy. Proper perioperative surgical technique is the key factor to the decrease of the serious complications.
