A total of 100 children up to 12 years of age admitted in three pediatric units of this hospital during the study period.

In addition, 25% had Atrial septal defect, 22% had Ventricular septal defect, 20% had Patent foramen ovale, 11% had Patent ductus arteriosus, 10% had Pulmonary stenosis, 4% had Tetralogy of Fallot. Conclusion: In conclusion we can say prevalence of CHD is increasing where both a trial septal defect and Ventricular septal defect are quite common. In addition, lower birth weight, gestational hypertension and diabetes are reported as risk factor developing CHD in neonates.
