OBJECTIVE: The purpose of this study is to review indications, surgical procedures, and outcomes in adults with repaired tetralogy of Fallot referred for reoperation. METHOD: Sixty consecutive adults (age >/= 18 years) who underwent reoperation between 1975 and 1997 after previous repair of tetralogy of Fallot were reviewed. Mean age at corrective repair was 13.3 +/- 9.6 years and at reoperation 33.3 +/- 9.6 years. Mean follow-up after reoperation is 5.0 +/- 4.9 years. RESULTS: Long-term complications of the right ventricular outflow tract (n = 45, 75%) were the most common indications for reoperation: severe pulmonary regurgitation (n = 23, 38%) and conduit failure (n = 13, 22%) were most frequent. Less common indications were ventricular septal patch leak (n = 6) and severe tricuspid regurgitation (n = 3). A history of sustained ventricular tachycardia was present in 20 patients (33%) and supraventricular tachycardia occurred in 9 patients (15%). A bioprosthetic valve to reconstruct the right ventricular outflow tract was used in 42 patients. Additional procedures (n = 115) to correct other residual lesions were required in 46 patients (77%). There was no perioperative mortality. Actuarial 10-year survival is 92% +/- 6%. At most recent follow-up, 93% of the patients are in New York Heart Association classification I or II. Sustained ventricular tachycardia occurred in 4 patients (7%) during follow-up. CONCLUSIONS: Long-term complications of the right ventricular outflow tract were the main reason for reoperation. Mid-term survival and functional improvement after reoperation are excellent.
