Background: Congenital heart diseases are the most prevalent congenital abnormalities in the neonates, caused by environmental and genetic factors and contributing to the leading cause of death. This study aims to evaluate the relationship between neonates with large for gestational age and increased risk of congenital heart diseases among non-diabetic mothers.
Methods: In this study, 179 neonates with large gestational age in Khorramabad were enrolled where heart abnormalities were evaluated using echocardiography.
Results: 87 neonates had more than 4000 g of birth weight with no heart abnormalities and 92 (51%) macrosomic neonates had congenital heart diseases. Statistical analysis revealed a significant relationship between birth weight and increased risk of acquiring congenital heart disease between the two groups. There was no significant relationship between birth weight, maternal age, gender, labor type and blood group between the two groups. The highest incidence of congenital heart anomalies was related to 38% of arterial septal defect (ASD) and 15.2% of ASD and VSD, respectively.
Conclusion: The most prevalent abnormality was arterial septal ASD. None of these abnormalities were associated with maternal age, birth weight and neonate gender. Future studies for congenital heart disease and neonatal birth weight are, therefore, recommended.
