ABSTRACT
OBJECTIVE: To identify delivery room (DR) characteristics of patients with transposition of the great arteries (TGA) who underwent preoperative balloon atrial septostomy (BAS).
STUDY DESIGN: Retrospective cohort study of all patients with prenatally diagnosed TGA delivered at our center between 2013 and 2023 who underwent arterial switch operation during the newborn admission.
RESULTS: A total of 168 patients were included (median gestational age 39.5 weeks, 64% male, 33% with ventricular septal defect [VSD], 8% with aortic arch hypoplasia). BAS was performed in 84 patients (50%). Patients who underwent BAS had higher proportion of intubation in the DR (87% vs. 33%, p<0.001), lower maximum oxygen saturation in the first 10 minutes (64% vs. 74%, p<0.001) and 20 minutes (71% vs. 81%, p<0.001) of life, and lower maximum oxygen saturation at any point in the DR (79% vs. 87%, p<0.001). Adjusting for confounders (VSD, aortic arch anomaly, 5-minute Apgar, birth weight), intubation in the DR (adjusted odds ratio [aOR] 9.5, 95% CI 3.9, 25.0) and lower maximum oxygen saturation in the DR (aOR 0.9, 95% CI 0.8, 0.9) were independently associated with BAS. By receiver operating characteristic analysis, a maximum oxygen saturation of less than 86% at any timepoint in the DR discriminated for BAS with a specificity of 0.88, sensitivity of 0.70, and area under the curve of 0.82.
CONCLUSIONS: Intubation and lower oxygen saturation in the DR are independently associated with BAS in patients with TGA born at our center. A maximum DR saturation of less than 86% best discriminates patients who undergo BAS in our population.
