Abstract:
Ovbective To evaluate the clinical results of simultaneous enlargement of the pulmonary annulus and the pulmonary cusp with a transannular patch of autologous pericardium in right ventricular outflow tract(RVOT)reconstruction. Methods From Jan.2003 to Jan.2004,Twenty-five patients who have complex congenital heart anomalies with pulmonary artery hypoplasia received surgical correction with RVOT reconstruction were randomly divided into research group (n=13) and control group (n=12). The patients in the research group used the technique of simultaneous enlargement of the pulmonary annulus and the pulmonary cusp with a transannular patch of autologous pericardium,routine technique of a transannular patch with or without a autologus pericardial monocuspid valve was used in control group. The main clinical characteristics and follow up data were studied and compared. The degree of pulmonary insufficiency was evaluated before discharge,at 3～6 months,and at 12months after the operation. Results There was no operative mortality in two groups. Compared with control group,the mean right ventricle to left ventricle systolic pressure ratio,right atrial pressure,maximum doses of dopamine and correction of pulmonary insufficiency were improved significantly (P
