Abstract:
Objective: To summarize the experience of clinical application of extracardiac valved tubes in complex congenital heart disease. Methods: From September 1979 to December 2001, 131 patients with complex congenital heart disease underwent surgical treatment by using extracardiac valved tubes, including 22 cases of aortic valved homografts, 73 cases of swine pulmonary valved tubes and 36 cases of extracardiac tubes with anti-calcified swine pericardium valve. Results: The overall mortality rate was 17.5%. The mortality rate has decreased to 10.7% in the late 10 years, and 4.5% in recent 5 years, respectively. Conclusion: It was suggested that aortic and pulmonary valved homograft preserved by liquid nitrogen is the first choice for extracardiac valved tubes. Extracardiac tubes with anti-calcified swine pericardium valve can also be used and they easily available. A better postoperative haemodynamic effect can be achieved by proper placement of the tubes, choice of suitable size and positioning in good geometrical figure.
