OBJECTIVES: The study aimed to evaluate the results following complete repair of tetralogy of Fallot (TOF) in relation to age at surgery and to assess the role of palliation in the current era. METHODS: A retrospective review of 251 consecutive patients with TOF repaired between 2003 and 2011 at the Great Ormond Street Hospital was performed. Children were divided into two groups: Group A, younger than 6 months (n = 78) and B, older than 6 months (n = 173). Early clinical outcomes and reoperation/reintervention rates were studied as well as indication for a palliation. RESULTS: There was 1 (0.4%) early and 1 (0.4%) late death after a median follow-up time of 4.5 years. Forty-three patients (17%) underwent repair after initial palliation with inter-stage mortality of 5%. Groups A and B were similar in terms of surgical approach, postoperative complications and length of stay. Significant differences were found in terms of more frequent use of a transannular patch (P = 0.05), longer surgeries (P = 0.02) and a greater proportion of palliated patients (P = 0.002) in older patients. There was no difference in rates of reoperation/reintervention between groups and following both primary and staged repair. Palliated patients were more symptomatic (duct-dependent pulmonary blood flow; P < 0.01, cyanotic spells; P < 0.01), had more extracardiac/genetic anomalies (P < 0.01), coronary anomalies (P = 0.015) and significantly smaller pulmonary annulus, right pulmonary artery (RPA) and left pulmonary artery (LPA) Z-scores (P < 0.01 for all). CONCLUSION: Age at complete repair was not linked to early clinical outcome or reoperation/reintervention rate. Palliative procedures postponed the timing of complete repair, but did not increase the reintervention rate.
