Congenital heart defects (CHD) remain one of the most common categories of birth defects
worldwide. In many developing countries, high early childhood mortality and limited diagnostic
facilities often obscure the true scope of the problem. In this review, we provide an overview of the
clinical epidemiology and management of CHD in a developing country: Nigeria, Africa's most
populous country. We describe the types of CHD and the clinical presentation, echocardiographic
diagnosis, management, and outcome of CHD. Ventricular septal defects are the commonest CHD
reported in Nigeria while tetralogy of Fallot is the commonest cyanotic CHD. Their etiology is often
unknown, although the congenital rubella syndrome and Down syndrome account for a signicant
minority of cases. Thus far, there is no modern genetic study of CHD in Nigeria. Diagnosis is often
delayed, with only about half of CHD cases getting diagnosed within the 1st year of life and up to
10% diagnosed in adulthood. Echocardiography has played a major role in improving diagnosis.
Management remains challenging, but a number of initiatives (especially by nongovernmental
organizations) provide access to corrective surgery for a select few. The eld of CHD in Nigeria
oers opportunities for research into etiology, natural history, clinical management, and outcomes.
