Attention-deficit/hyperactivity disorder symptoms in children with surgically corrected Ventricular Septal Defect, Transposition of the Great Arteries, and Tetralogy of Fallot

BACKGROUND: Children with complex CHD are at risk for psychopathology such as severe attention-deficit/hyperactivity disorder symptoms after congenital heart surgery.

OBJECTIVE: The aim of this study was to investigate if children with Ventricular Septal Defect, Transposition of Great Arteries, or Tetralogy of Fallot have an increased occurrence of attention-deficit/hyperactivity disorder symptoms compared with the background population and to investigate differences between the three CHDs in terms of occurrence and appearance of attention-deficit/hyperactivity disorder symptoms.

METHOD: A national register-based survey was conducted, including children aged 10-16 years with surgically corrected CHDs without genetic abnormalities and syndromes. The Attention-Deficit/Hyperactivity Disorder-Rating Scale questionnaires were filled in by parents and school teachers.

RESULTS: In total, 159 out of 283 questionnaires were completed among children with CHDs and compared with age- and sex-matched controls. Children with CHDs had significantly increased inattention scores (p = 0.009) and total attention-deficit/hyperactivity disorder scores (p = 0.008) compared with controls. Post hoc analyses revealed that children with Tetralogy of Fallot had significantly higher inattention scores compared with children both with Ventricular Septal Defect (p = 0.043) and controls (p = 0.004).

CONCLUSION: Attention-deficit/hyperactivity disorder symptoms and inattention symptoms were significantly more frequent among children aged 10-16 years with CHDs, in particular in children with corrected Tetralogy of Fallot.
