Abstract

Background: Congenital heart defects are the singular most common congenital anomalies and account for a significant fraction of childhood mortality and morbidity. Hearing impairment was the most frequent sensory deficit. Auditory brainstem response (ABR) was determined to assess the maturation and function of brainstem, and hence, hearing in infants. Therefore, we used ABR for hearing assessment in infants diagnosed with congenital heart disease. Methods: This observational cross-sectional study was carried out on 60 infants, below or above the age of 12 months, both sexes, with CHD. Infants were furtherly divided into two equal groups: Group A with a cyanotic infant, and group B with cyanotic infants. All patients were subjected to Echocardiography. Results: 20% of our cases to be affected with varying degrees of hearing loss. No significant difference was found between the cyanotic and a cyanotic infant. However, cyanotic infants below 12 months had higher incidence of hearing loss when compared to those above the age of 12 months; whether the cyanotic or the cyanotic peers. Conclusions: High prevalence of hearing loss amongst patients with CHD warrants the addition of those patients to the high-risk registry for hearing loss, in order that they may benefit from early detection and intervention, and ergo protected against the affection of hearing impairment on their neurodevelopment. Routine follow-ups for patients with cyanotic heart disease from the age of 6 months to assess the effect of chronic hypoxemia on the inner ear and monitor the rate of improvement in ABR results, as to establish an accepted rate of improvement, and an appropriate time of intervention, if needed.
