Inattention and hyperactivity in children and adolescents with repaired D-transposition of the great arteries: Prevalence, perioperative risk factors, and clinical outcomes

ObjectiveThe present study objectives were to determine the prevalence of attention-deficit/hyperactivity disorder symptoms (ADHD-like symptoms) in children and adolescent with d-transposition of great artery (D-TGA) after arterial switch operation (ASO) and examine associated risk factors and adverse personal, family dysfunctions. MethodsThis cohort study included 103 patients with D-TGA who underwent ASO in early infancy at Shanghai Children's Medical Center between 2011 and 2016 and then follow-up. Data analysis was conducted from September 2020 to April 2022. A standardized Swanson, Nolan, and Pelham IV (SNAP-IV) questionnaire is used to evaluate inattention and hyperactivity symptoms. Demographic, preoperative, intraoperative, and postoperative factor were collected. Univariate and multivariable regression analyses were performed with odds ratios (OR) and 95% confidence intervals (CIs). ResultsPrevalence of ADHD-like symptoms was 27.18% (28/103). Attention-deficit (18/28, 64.29%) symptom was the predominant subphenotype. After underwent TGA surgery, 39% of patients with ADHD-like symptoms receive remedial special academic services. There is none had repeated grade. Univariate analysis showed that, positive inotropic drug score (P = 0.03) and delayed sternal closure (P = 0.02) were risk factors of ADHD-like symptoms; increased preoperative oxygen saturation (SpO(2)) (P = 0.01) and surgical height (P = 0.01) and TGA subtype (VSD) (P = 0.02) were protective factor of ADHD-like symptoms. Multivariable analysis showed that delayed sternal closure (DSC) (OR, 1.50; 95% CI, 1.02-2.18) is a risk factor for the occurrence of ADHD-like symptom while increased preoperative oxygen saturation [odds ratio (OR), 0.95; 95% confidence interval (CI), 0.92-0.99] is a protective factor of ADHD-like symptom. ConclusionThe children and adolescents with D-TGA after ASO were at high risk of ADHD-like symptoms. Preoperative hypoxic status and postoperative DSC became predominant risk factors. Modification of the risk factors may be helpful to relieve ADHD-like symptoms for these patients.

Automated summary

This study investigated the prevalence of attention-deficit/hyperactivity disorder symptoms (ADHD-like symptoms) and associated risk factors in children and adolescents with d-transposition of the great artery (D-TGA) who underwent arterial switch operation (ASO). The results showed that preoperative hypoxic status and delayed sternal closure were major risk factors for ADHD-like symptoms.
