Children born with a congenital heart malformation and requiring early open heart surgery are at-risk for various types of developmental delays, according to an MUHC study.

With a new environment, new friends and new activities, the first day of school is a big step in the lives of young school-age children and one that requires all their cognitive, motor and social-emotional skills. This challenge is even greater for those born with a congenital heart malformation and who underwent open-heart surgery soon after birth. In her latest study, Dr. Annette Majnemer, from the Research Institute of The Montreal Children鈥檚 Hospital at the MUHC, has assessed the developmental difficulties in these children and provided keys for possible prevention. Her article was recently published in The Journal of Pediatrics.

鈥淥ur results show that these young 鈥榮urvivors鈥� of heart surgery at birth are more likely to have difficulties in school,鈥� Dr. Majnemer explained. 鈥淭hese difficulties can be linked to their learning abilities, as the average IQ of the surveyed patients was average or low, with 22% having an IQ below 80. Also, 27% of these children experience behaviour problems that often lead to challenges in social development and, later, with lower self-esteem.鈥�

The patients involved in this study were tested at birth and early infancy, at 18 months and at five years. A careful assessment before surgery revealed nervous system anomalies in more than 50% of the newborns who were to have open-heart surgery soon after birth, as well as in over a third of the infants who were to have it a bit later in life. It is therefore very probable that the heart malformation is associated with a lack of adequate oxygen supply to the brain early in life, or even before birth, which hampers the child's development independent of the surgery. This would also explain the researchers鈥� clear finding that the older the child at the time of the operation, the lower his or her IQ.

鈥淲e need to understand the mechanisms that cause this delay in cognitive development as well as other developmental domains in children born with a congenital heart malformation,鈥� Dr. Majnemer stated. 鈥淭his will give us a case to promote early intervention and therefore help prevent or minimize developmental delays in a number of children. It will also give families access to better quality information to help them make informed choices about services needed and enable them to better monitor their children.鈥�

Monitoring the global development of children who have undergone this surgical procedure has not yet been established as standard health practice in Canada. However, a developmental surveillance program is in place at the Montreal Children's Hospital for newborns diagnosed there. 鈥淲e hope that this study will be a first step towards generally implementing developmental screening and timely referral to rehabilitation and educational specialists if needed, as this is a common request from the families of patients,鈥� Dr. Majnemer recommended.
