[Application of homologous conduits with valves in the treatment of complex congenital heart disease with insufficient pulmonary blood flow in children].

Objective: To investigate the effects of homologous conduits with valves in the treatment of complex congenital heart disease with insufficient pulmonary blood flow in children.
Methods: Homologous conduits with valves were used in the right ventricular outflow tract reconstruction among 212 pediatric patients with complex congenital heart disease with insufficient pulmonary blood flow, aged 2.6 (0.5 - 15). The patients were followed up for 2.6 years (6 months to 7 years) and underwent echocardiography to assess the degree of pulmonary insufficiency and calcification of blood vessel.
Results: The success rate of operation was 96.5% (204/212). The ratio of right ventricle to aortic pressure was less then 0.55. During the follow-up, echocardiography showed valvular regurgitation and calcification of the blood vessel in 34 patients, 23 (11.2%) being mild, 7 (3.42%) being moderate, and 4 (1.96%) being sever. 170 patients did not show obvious pulmonary insufficiency.
Conclusion: Application of homologous conduits with valves in the treatment of complex congenital heart disease with insufficient pulmonary blood flow in children shows excellent early results in preventing pulmonary insufficiency.
