Abstract
Congenital heart disease (CHD) is 1/3 of all congenital malformations and one of the main causes of infant mortality. Hearing loss may be part of syndromes associated with CHD, or the hearing pathology can be a consequence of the various stages of rehabilitation of underlying pathology. Currently, there isn’t any data on the systematic study of hearing impairment in children with congenital cardiac pathologies. Three hundred and six patients aged 2 days to 8.5 months were examined: 96 patients were included in the main group with CHD, and 300 children without CHD made up a comparison group. All children underwent newborn hearing screening. Infants with suspected hearing pathology were tested with a comprehensive audiological examination. In the CHD group hearing impairment was detected in 29% of children, including sensorineural hearing loss (SNHL) in 12%. And in the comparison group, 3.6% of infants had a hearing loss, SNHL was defined in 1%. Analysis of the data revealed the most significant risk factors for hearing impairments in children with CHD and it had showed the difference in the structure of the risk factors between the both groups. In the study group was registered a case of auditory neuropathy spectrum disorders. This case illustrated the importance of conducting hearing screening by means of click-evoked auditory brainstem responses and not only of registration of otoacoustic emissions. One child with CHD was found to have delayed SNHL, which requires long-term monitoring of hearing in children with cardiopathology.

Summary
St Petersburg State Pediatric Medical University, Ministry of Healthcare of the Russian Federation, Russia. In the CHD group hearing impairment was detected in 29% of children, including sensorineural hearing loss (SNHL) in 12%. Analysis of the data revealed the most significant risk factors for hearing impairments in children with CHD and it had showed the difference in the structure of the risk factors between the both groups. In the study group was registered a case of auditory neuropathy spectrum disorders This case illustrated the importance of conducting hearing screening by means of click-evoked auditory brainstem responses and of registration of otoacoustic emissions. Находившихся на лечении в отделениях интенсивной терапии новорожденных, патология слуха встречается у 20–40 на 1000 младенцев. Нарушение слуха может быть частью синдромов, ассоциированных с ВПС.
