Correction of tetralogy of Fallot and of pulmonary atresia with ventricular septal defect in adults.

Background: Early correction is regarded as the treatment of choice for patients with tetralogy of Fallot or pulmonary atresia with ventricular septal defect. Nevertheless, some of these patients reach adulthood without early correction. This study sought to assess risk factors for operative mortality and determine the benefit of total correction in adolescent and adult patients.
