Background: Congenital heart disease (CHD) is one of the most common congenital defects worldwide. The prevalence of CHD is low in India mostly due to under detection. The knowledge regarding socio-demographic factors, other congenital anomalies/syndromes and social impacts associated with CHDs in India is grossly lacking.

Methods: This was a retrospective study. Details of all diagnosed pediatric (age 0-14 years) cases of CHD were recorded by a single cardiologist from the year 2013 to 2020. Duplicate entries were removed and CHDs were classified according to Q20-Q28 of tenth revision of international classification of diseases (ICD). For description purposes, the CHDs were divided into 10 sub-groups.

Results: Total 9247 cases of CHDs were recorded during the study period. Ventricular septal defect was the most commonly identified CHD (32.1%). Most cases were acyanotic (69.8%) and presented first time at age of more than two years. Almost 1.5% cases were associated with other non-cardiac congenital defect or syndrome. In 1.0% of cases either mother or the child faced social or family problem due to the disease.

Conclusions: CHD is an emerging public health problem. It is associated with other congenital anomalies/syndrome. Mandatory screening for birth defects needs to be initiated at all birth facilities. At birth counseling of the parents need to be implemented due to the associated social issues.
