Although most patients with tetralogy of Fallot (TOF) undergo radical repair during infancy and childhood, patients remaining undiagnosed and untreated until adulthood can still betreated. These patients have either a previous palliative or natural collateral circulation to the lung or a mild form of right ventricular outflow tract (RVOT) obstruction. The aim of this study is to analyze the perioperative and long-term results of radical corrective procedures in patients who reached adult ages. Two hundred and seven patients with TOF underwent complete correction between 1985-and 2002, 64 (30.9%) of whom were aged 14 years or more. The mean age at corrective repair for this group was 20.6 +/- 7.5 years (range 14 to 49 years). Only two patients had previous modified Blalock-Taussig shunts. In 44 patients (68.7%) besides infundibular resection, a transannular gluteraldehyde-treated pericardial patch was used to reconstruct right ventricular outflow tract [RVOT). Only infundibular patching was used in 15 patients (23.4%) and infundibular muscular resection with primary closure of right ventricle was performed in five patients 17.8%). Hospital mortality was 3.1% with two patients. Four patients (6.2%) underwent reoperation because of recurrent ventricular septal defect (VSD) with/without residual obstruction or pulmonary regurgitation. All survivors were in NYHA class 1 (42) or 11 (17). Late mortality was recorded in two patients and 16-year actuarial survival was 89.2% +/- 4.9%. The significant negative predictors of late survival determined by univariate analysis were reoperation < 0.018) and associated cardiac anomalies < 0.011). Multivariate analysis showed that there was no negative predictor of late-term mortality. Corrective procedures in adult patients with TOF can be performed successfully compared to patients who underwent operation during infancy and childhood.
