RESUMO
Congenital heart defect (CHD) is the most common birth defect & a significant cause of childhood morbidity & mortality. Structural brain abnormalities are more common in children with CHD than general population. This study details the cognitive, motor and behavioral development of a child with congenital heart disease who is on medical management. In this retrospective descriptive study, abnormalities in neurobehavioral status of infant & children (6-42 months of age) with CHD, who are on medical management were assessed by a standardized neurobehavioral assessment test, BSID-II. Fifty-eight children were included, who were diagnosed as a case of congenital heart disease & confirmed by Colour Doppler echocardiography in the Paediatric Cardiology Department of Bangabandhu Sheikh Mujib Medical University, Bangladesh. Mean age of the children was 23±13 months (range, 6 to 42 months); M:F = 1:1.9. Among them 22(37.9%) had cyanotic and 36(62.1%) had acyanotic congenital heart disease. Neurobehavioral and neurologic abnormalities were documented in a significant number of children. BSID-II showed 23(39.7%) had delayed metal development, 24(41.4%) had motor impairment and 16(27.6%) had non-optimal behavioral performance. Interestingly, infant and young children with acyanotic congenital heart defects were more likely to demonstrate severe neurologic compromise than were those with cyanotic defects. Findings of this study suggest that the prevalence of neurobehavioral abnormalities in infants and young children with congenital heart defects has been under predicted & indicates that delay in closure (surgery/device) puts the patient at an increased risk of neuro-developmental insult.
