Neurodevelopmental Status of Children Aged 6-30 Months With Congenital Heart Disease

Background: Children with congenital heart diseases (CHD) are considered to be at high-risk for neurodevelopmental delay, but scant Indian data are available. Objective: To evaluate the neurodevelopmental status of children with CHD. Methods: We enrolled consecutive children aged 6-30 months with echocardiographically-confirmed CHD between June 2013 and January 2014. Children with clinically recognizable genetic syndromes or disorders; visual and/or hearing deficits, and nnicrocephaly; and post-cardiac surgery children were excluded. Development was assessed by Developmental Assessment Scale for Indian Infants (DASII) and Developmental delay defined as Development Quotient (DQ) <70 in either the mental or motor scale. Results: 75 children (53 males) with CHD were enrolled. Acyanotic CHD was seen in 51 children (VSD in 47%), and Tetralogy of Fallot was the commonest cyanotic CHD (25%). Developmental delay was seen in 25% of these children, more in the motor domain (48%) than in mental (12%). Mean motor and mental DQ in acyanotic CHD was 77 and 84, respectively; and 65 and 85, respectively in cyanotic CHD. Mean motor DQ was significantly less than mental DQ in both acyanotic and cyanotic CHD children (P=0.048). Conclusion: Children with CHD are at an increased risk for developmental delay. Periodic surveillance, screening and evaluation should be instituted in them for early identification and appropriate interventions to enhance later academic, behavioral, psycho-social and adaptive function.
