    Abstract:
    OBJECTIVE: To evaluate the application value of right ventricular outflow tract (RVOT) reconstruction with an autologous pericardial monocuspid valve to prevent pulmonary regurgitation after total correction of tetralogy of Fallot (TOF). METHOD: Twenty patients suffering from TOF with pulmonary artery hypoplasia, 11 males and 9 females, aged (8.43+/-3.83), received surgical total correction with RVOT reconstruction with autologous pericardial monocuspid valve. During the operation, the RVOT was enlarged with the autologous pericardial patch, and a predesigned part of the pericardial patch was folded to form a big artificial valve, which was stitched along with the pericardial patch. Another 20 patients, 12 males and 8 females, aged (8.47+/-3.94), underwent traditional RVOT reconstruction with traditional pericardial monocuspid valve patch. Post-operational follow-up was conducted for 6 months. RESULTS: No surgical mortality was recorded after operation. The degree of pulmonary valve regurgitation in the research group was less than that in the control group. CONCLUSION: Modified autologous pericardial monocuspid valve can prevent pulmonary regurgitation better.
