The progress of cardiac surgery in children and the increase in the survival of children with Congenital Heart Disease (CHD) has led to consider another issue called a neurodevelopmental disorder. In this study, 53 children with CHD were evaluated in terms of development with the Essence Q questionnaire, Otoacoustic Emission (OAE), and Auditory Brainstem Response (ABR) regarding these patients’ hearing and risk factors. The Essence Q scores were also examined

Materials & Methods

In this prospective, cross-sectional study, the researchers included 53 children diagnosed with CHD. Initially, each child underwent ABR and OAE tests. Subsequently, data on potential risk factors associated with neurodevelopmental delay were collected. A trained project associate administered the Essence Q questionnaire, using parents’ information as a guide. Following data collection, this study proceeded with an in-depth analysis of the information.


Thirty-six boys (67.92%) and 17 girls (32.08%) with CHD were included in the study. The mean age of children was 2/23+_8.11. The mean Essence Q score for boys was 7.48+_2.57.
Moreover, the average score for girls was 2.23 8.11. According to this questionnaire, 39 patients (73.58%) had hyperactivity disorder,46 patients (86.79%) had behavioral disorders, and ten patients (16.98%) had a motor delay. Unlike previous studies, all patients had normal OAE and ABR hearing.


This study demonstrated that factors such as developmental delay in the first year, a known genetic disease, and a history of seizures significantly impacted the Essence Q score. However, elements like prematurity, the use of ventilation, abnormalities on the dorsum, and the number of days post surgery did not significantly affect the Essence Q score. Essence Q can be a reliable tool in screening for neurodevelopment in children with CHD
