Persistence of visuo-constructional and executive deficits in adolescents after open-heart surgery

This study assesses whether previously reported performance deficiencies in visuo-constructional and executive functions, using the Rey-Osterrieth Complex Figure Test (ROCFT) in pediatric patients with congenital heart disease (CHD), persist into adolescence.

53 adolescent CHD patients (mean age 13.7) and 39 healthy controls (mean age 14.1) participated. ROCFT performance was measured by three different scoring methods, focusing either on quantitative (Meyers & Meyers, 1995), qualitative (Wallon & Mesmin, 2009), or both performance aspects (Bernstein & Waber, 1996). Potential confounders (i.e., intelligence and visuomotor integration) and surgery-related risk factors were included in the data analysis.

Adolescents with CHD demonstrated immature copy and recall approaches on the ROCFT using the qualitative system by Wallon and Mesmin (p<.001). Memory performance was also predicted by Bernstein and Waber scores (p<.03), whereas group differences were not significant according to the other scoring methods. Intelligence and visuomotor skills, but not surgery-related risk factors, were positively correlated with ROCFT performance (each p<.02). Interpretation: Visuoconstructional and executive deficiencies could be found in adolescent patients with CHD. However, not all ROCFT scoring methods were equally apt to detect group differences: especially the qualitative scoring method developed by Wallon and Mesmin seems sufficiently sensitive to detect long-lasting visuo-constructional and executive deficiencies in CHD patients.
