The prevalence of structural congenital heart disease is approximately 6-10 per 1,000 total births (~1%).
The incidence of heart murmurs on day 1 examination, however, may be as high as 10% live births. This prompts echocardiography, of which 9/10 will be normal or have a transitional neonatal circulation (PDA and/or PFO).
The antenatal diagnosis of serious congenital heart disease is only 50%.
