burden of congenital heart diseases in a tertiary cardiac care institute in western india: need for a national registry

Objective: Congenital heart disease (CHD) is very common disease, and it is the major cause of childhood mortality and morbidity. Not much of Indian data are available particularly from the western part of the country. There are needs to further explicate the spectrum and epidemiology of the CHD. Materials and Methods: This retrospective study collected data of the paediatric patients received in our institute from January 2016 to June 2017. All simple and complex congenital anomalies diagnosed on echocardiography were included in our study. Results: Of total 22,275 cases, CHDs were diagnosed in 9728 cases with a male-to-female ratio of 1:0.6. Most CHDs (62.77%) were diagnosed between 1 month and 6 years of age. Incidence of cyanotic CHD was 27.14% and acyanotic CHDs was 72.86% with a ratio of cyanotic-to-acyanotic CHD being 1:2.7. Ventricular septal defect (26.24%) was the most common acyanotic CHD found followed by 2089 patients of atrial septal defect. Tetralogy of Fallot (13.57%) was the most common cyanotic CHD found followed by double-outlet right ventricle in 276 patients (2.84%). Conclusions: Ours is the largest Indian study till date in this spectrum which yielded new data on the epidemiology, incidence, and prevalence of CHD. Majority of the patients with CHD had acyanotic CHD with most common anomaly being ventricular septal defect. Tetralogy of Fallot was the most common cyanotic defect. This study will increase awareness in the people with a family history of CHD and health-care providers and will assist in early diagnosis.
