Frequency of congenital heart disease using ecocardiography in patients with extra-cardiac anomalies in gorgan peadiatric center, north of Iran (2012-17)

Background and Objective: Congenital anomalies are one of the major causes of neonatal mortality. Congenital heart disease (CHD) is the most common birth defect world wide, and recent studies about CHD have reported congenital heart disease approximately is about one percent of all live births. This study was done to determine the frequency of congenital heart disease using ecocardiography in patients with extra-cardiac anomalies in Gorgan peadiatric center in north of Iran. Methods: In this descriptive study, 55 girls, 84 boys a total of 139 patients were in the age range of birth to 12 years of age whom have referred to Taleghani Teaching and Medical Center in Gorgan during 2012-17. 139 cases of congenital heart disorders with echocardiographic report sheet in their medical record were evaluated. Information of patients including age, sex, ethnicity, type of extra-cardiac, anomalies, cardiac anomalies (simple, complex and ductal anomalies), cardiac murmur status, and clinical symptoms were extracted from their medical records. Results: From of total of echocardiography, 139 patients (88.5%) were affected by congenital heart disease. The anomalies were included of 88 cases (56.05%), 48 cases (31.21%), 2 cases (1.27%) simple, complex anomaly and ductal dependent anomaly respectively. The other disorders accompanied with congenital heart diseases were 17 cases (12.2%) with cleft palate, 4 cases (2.9%) with congenital diaphragmatic hernia, 8 cases (5.8%) with closed anus, 52 cases (37.4%) with Down syndrome, 4 cases (2.9%) with Turner syndrome, 4 cases (2.9%) with ileum atresia, 11 cases (7.9%) with Esophageal atresia, 7 cases (5%) with Hirschsprungchr('39')s disease, 6 cases (4.3%) with urogenital anomalies and 26 cases (18.7%) with other extra-cardiac abnormalities. Conclusion: Down syndrome and cleft palate are among the highest prevalant anomalies with congenital heart diseases.
