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 center 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 2001-2022. 37 children had TBA, 13 TGA, 5 of them an interrupted AA. Median age at operation was 7 (IQR 5-9) days, weight 3.38 (IQR 2.9-3.8) kg, follow-up 9.3 (IQR 3.1-14.5) years. The AA reconstruction was performed without patch material in 49 cases. RESULTS: There was one in hospital mortality in a TBA patient and one late mortality (7 years later, neuroblastoma). 14/49 patients needed at least one reoperation (28.6%, all TBA), 3 further patients had catheter reintervention or radiofrequency ablation only (6.1%, 2 TBA). 75% of these procedures affected the right heart/pulmonary arteries, there was one re-coarctation repair. CONCLUSIONS: The simultaneous correction of TBA and TGA with AA obstruction or interruption is a safe operation with very low mortality. The AA reconstruction with minimized use of patch material resulted in a low restenosis rate.
