Background and Objectives
Mental health outcomes for survivors of critical congenital heart disease (CHD) remain under-investigated. We sought to examine psychiatric disorders and psychosocial functioning in adolescents with single ventricle CHD and to explore whether patient-related risk factors predict dysfunction.
Methods
This cohort study recruited 156 adolescents with single ventricle CHD who underwent the Fontan procedure and 111 healthy referents. Participants underwent comprehensive psychiatric evaluation including a clinician-rated psychiatric interview and parent- and self-report ratings of anxiety, disruptive behavior – including attention deficit hyperactivity disorder (ADHD), and depressive symptoms. Risk factors for dysfunction included IQ, medical characteristics, and concurrent brain abnormalities.
Results
Adolescents with single ventricle CHD had higher rates of lifetime psychiatric diagnosis compared with referents (CHD: 65%, referent: 22%; P<0.001). Specifically, they had higher rates of lifetime anxiety disorder and ADHD diagnosis (P<0.001 each). The CHD group scored lower on the primary psychosocial functioning measure, the Children’s Global Assessment Scale (CGAS), than referents (CHD median [interquartile range]: 62 [54–66], referent: 85 [73–90]; P<0.001). The CHD group scored worse on measures of anxiety, disruptive behavior, and depressive symptoms. Genetic comorbidity did not impact most psychiatric outcomes. Risk factors for anxiety disorder, ADHD, and lower CGAS scores included lower birth weight, longer duration of deep hypothermic circulatory arrest, lower intellectual functioning, and male gender.
Conclusions
Adolescents with single ventricle CHD display a strikingly high risk of psychiatric morbidity, particularly anxiety disorders and ADHD. Early identification of psychiatric symptoms is a key component of the management of patients with CHD.
