Parents reported language development and scholastic achievement in children with congenital heart diseases versus typically developed

Children with congenital heart diseases (CHD) may have developmental delays including delayed language development (DLD) and learning difficulties. The purpose of this study was to observe the effects of CHD on language developmental profile and scholastic achievement (SA) with particular emphasis on prevalence of DLD and SA, potential risks, and need for early intervention. This case–control study included 158 children with CHD and 145 healthy children as controls. Participants’ ages ranged from 6 months to 15 years. Data were collected by reviewing clinical records and questionnaires covering potential risks, motor and language development, and SA. Potential risks were analyzed using the Fisher test, while language development and SA were compared using Mann–Whitney test. The incidences of parent consanguinity, family history of DLD, and neonatal cyanosis were higher than expected by chance in the CHD group with p-values which are < 0.001, 0.044, and < 0.001, respectively. The CHD group revealed more delay in babbling, first word production, two-word sentences, three-word sentences, narration, and SA than control group with significant differences. These comparisons’ p-values are 0.002, < 0.001, 0.009, 0.029, 0.03, and 0.042 respectively with mean effect size 0.3. The language development profile in cyanotic HD showed more delay than acyanotic HD with significant differences. The DLD and affected SA were more prevalent in children with CHD. The risk for DLD in CHD children was multifactorial; however, the main predisposing factor was chronic hypoxia that starts in the intrauterine life in CHD. Neonates with CHD require early intervention through oxygen therapy before surgery. Early family counseling and language therapy are recommended to improve quality of life through achieving better communicative ability and academic skills. Further studies which concerned the effect of maternal oxygenation on prognosis of fetuses with CHD may be required. Also, duplication of the study including formal testing is recommended.
