Abstract: 

The results of a retrospective study of newly diagnosed cases of congenital heart defects (CHDs) among liveborn infants in the Sakha Republic (Yakutia, SR(Y)) are presented. The study was divided into two time periods: Period A (from 2002 to 2002) and Period B (from 2011 to 2013). A comparative analysis of the prevalence of CHD detection and the structure of clinical entities of CHDs among liveborn infants in Period A (42,827 liveborn infants and 186 cases of CHDs) and Period B (50,104 liveborn infants and 899 cases of CHDs) was performed. The prevalence of CHDs among newborns in Period A was 4.34 per 1,000 live births, which corresponded to the average CHD frequency in Russia. The prevalence of CHDs among newborns in Period B was 17.9 per 1,000 live births, which is significantly higher than in Period A (P=0.0000). The overall growth of the incidence of CHDs among newborns in period B was due to an increase in the prevalence and frequency of septal defects. The increase in the prevalence of CHDs could be due to many factors, including improvement in the quality of diagnosis in 2011–2013.
