Objective A surgical team has performed total correction of Tetralogy of Fallot (TF) con-secutively in 115 patients without surgical, death. This paper presents an investigation of how to improve the sur-gical outcome. Methods This group included 115 children, the ages of these children at operation were from 9 months to 13 years (4.6 ± 2. 7 years), 47.8% of whom were younger than 3 years old. Associated anoma-lies included atresia of main pulmonary artery or unilateral pulmonary artery in 4 cases, a trial septal defect (ASD) and patent ductus arteriosus (PDA) in 11 cases. All patients have undergone total correction. Ventri-cular septal defects were closed with Dacron patches. Autologous-pericardial patches were used to enlarge the right ventricular outflow tract and pulmonary arteries. 102 cases (89%) needed transannular patches. Re-sults There was no surgical death and the patients have been followed up for 2 months to 4 years. One child died of cardiac arrhythmia 3 months after operation. The remaining patients recovered well. Conclusion The key points in improving the surgical outcome in TF patients lie in the improvement of surgical technique, total elimination of obstruction of right ventricular outflow tract and distal pulmonary arteries. Attention should be paid to the cardiopulmonary bypass and the postoperative care should also be emphasized.
