Objective To summarize the experience of radical treatment of tetralogy of fallot in adults.Method Between Nov. 1985 and May 2005,115 patients over 18 years of age with tetralogy of fallot underwent total surgical correction.Longitudinal or oblique right ventriculotomy was used to ensure complete release right ventricular outflow obstruction and complete ventricular septal defect closure.Transannular patches were used in 74 patients,right ventricular outflow tract(RVOT) patches in 37 cases,primary closure of right ventricle in 5 cases,respectively.One patient had separate pulmonary main artery and RVOT enlargement.Results Seven patients had residual septal defect and 3 cases suffered from residual RVOT obstruction.Severe cardiac output syndrome occurred in 10 patients and 6 patients died early postoperatively with the mortality rate of 5.22%.Conclusion By careful surgical management,the treatment of total correction in adult patients may result in good effectiveness.
