[Effects of right ventricular outflow tract reconstruction with modified autologous pericardial monocuspid valve in patients with tetralogy of Fallot: a clinical research].
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).


METHODS
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.


CONCLUSIONS
Modified autologous pericardial monocuspid valve can prevent pulmonary regurgitation better.
