Introduction • Definition An abnormality in cardiocirculatory structure or function that is present at birth , even if it is discovered much later • Prevalence CHD occurs in 0.5-0.8% of live births,About 2-3 in 1,000 newborn infants will be symptomatic with heart disease in the first year of life. • The diagnosis is established by 1 week of age in 40- 50% of patients with CHD and by 1 month of age in 50-60% patients
