  • *Excluding 218 children with no ethnicity record; IRs per 10 000 infants aged 0–1 years calculated using eligible cases in audit data from 2006–2009; binomial exact method used to estimate CIs for; IRR>1.0 and related CIs shown in bold type. Cell counts <5 are suppressed to reduce disclosure risk. Miscellaneous primary cardiac diagnoses are a group of very rare but severe primary diagnoses, whereas miscellaneous congenital terms comprise miscellaneous structural cardiac defects of varying severity, which are not recognised as distinct primary diagnoses. Isolated subaortic stenosis and aortic regurgitation not shown as ≤10 children per subgroup.

  • ASD, atrial septal defect; AVSD, atrioventricular septal defect; DORV, double outlet right ventricle; PDA, patent ductus arteriosus; TGA, transposition of the great arteries; VSD, ventricular septal defect.
