Evaluation of the Prevalence of Congenital Heart Diseases in neonates of Ilam province of Iran, in 2019-2020

Congenital heart diseases (CHDs) can cause death and severe disorders in the developmental process of children and, in most cases, are associated with other congenital defects. The current study investigates the prevalence of such defects among infants born in 2019 and 2020. This analytical cross-sectional study was conducted in Ilam province on 91 referred neonates, with the possibility of heart diseases, who were diagnosed with CHDs. Demographic, clinical, and definitive diagnoses of cardiologists were recorded and analyzed in these infants, followed by a 6-month follow-up. Data were analyzed using SPSS software with descriptive statistics, Chi-square test, and correlation coefficients. A total of 91 infants out of 16,064 newborns were diagnosed with CHDs, and the prevalence of heart diseases was 5.9 in every 1000 live births. The most frequent defects were ventricular septal defects (VSDs) and PDA, with prevalence rates of 59.3% and 14.2%, respectively. Among 54 VSDs, mus VSD (n = 39) was the most common form of this disorder. The incidence of CHDs in Ilam province was lower than the global average, which may be attributed to the easier access of several cities to the health centers of the bordering provinces. The highlighted results of this study were the frequency of VSDs and the high rates of muscular VSD compared to membranous VSD.
