Methods: In this descriptive-analytical cross-sectional study, the study population included 300 patients with congenital heart disease, who were referred to Pediatric Cardiac Clinic. The data collection tool was a checklist form, which was used to complete the information contained in the patient records and contact with their parents. The collected data were analyzed by SPSS software and statistically analyzed by x2 statistical test at a significant level of p≤0.05.

Results: The mean age of children with congenital heart disease at the time of diagnosis was 1.25 ± 2.92 years. 156 (52%) were male. The most common type of congenital heart disease included ventricular septal defect (28.7%), patent ductus arteriosus (18.2%), and atrial septal defect (14.6%). In 57% of cases, there was a familial relationship between parents. Down syndrome with an incidence of 3.8% was the most common anomaly. There was a significant statistical difference between each of the above variables and the beginning of pregnancy with the distribution of congenital heart disease in the children p≤0.05.

Conclusion: According to results, considering a proper screening program and conducting classes especially for high-risk groups, advise to Pregnancy at an early age, avoidance of medication during pregnancy, and avoid family marriage seem necessary.
