Long-term follow-up after simultaneous arterial switch operation and aortic arch repair

Abstract

OBJECTIVES: Taussig–Bing anomaly (TBA) and transposition of the great arteries (TGA) with hypoplastic or interrupted aortic arch (AA) are rare anomalies. Various operative techniques and a high incidence of reinterventions are described. The aim of this retrospective single-centre study was to evaluate operative data, mortality and reintervention rate with special regard to the AA. METHODS: At the Children’s Heart Center Linz, 50 patients with the above-mentioned diagnosis have been corrected by a simultaneous repair between 2001 and 2022. Thirty-seven children had TBA, 13 had TGA and 5 of them had an interrupted AA. The median age at operation was 7 [interquartile range (IQR) 5–9] days, weight 3.38 (IQR 2.9–3.8) kg and follow-up 9.3 (IQR 3.1–14.5) years. The AA reconstruction was performed without patch material in 49 cases.
