The clinical profile and surgical treatment of tetralogy of Fallot in the adult: results of repair in 200 patients

Abstract This report describes our 17-year experience with intracardiac repair in 200 patients older than 14 years with tetralogy of Fallot. Congestive failure, hemoptysis, and cerebral abscess were present in 15, 10, and 3% of patients, respectively. Prior palliative shunts had been performed in 24.5% only. Polycythemia with a hematocrit greater than 60% was noted in 100 patients but was not considered an incremental risk factor ( p > 0.05). A transannular gusset was utilized in 74% of patients in the last 5 years of the study. Hospital mortality was 1.3% in the last 5 years. Ninety-seven percent of survivors at follow-up are asymptomatic and leading an active life. Recatheterization data from 86 patients revealed excellent or good results in 88%. The incidence of residual ventricular defect was 1% overall, with a zero incidence in the last 12 years. On the basis of this review, we consider that easier and hemodynamically satisfactory repair has been achieved in the adolescent and older patient compared with the child. The ultimate longevity, however, must await the results of long-term functional and serial hemodynamic evaluation.
