Table 3 Examples of descriptions of common congenital heart disease in the segmental sequential nomenclature

CHD type	Sequential segmental analysis
Ventricular septal defect	Normal atrial arrangement, concordant atrioventricular and ventriculo-arterial connections, levocardia
Ventricular septal defect	+ VSD
Aortic coarctation	Normal atrial arrangement, concordant atrioventricular and ventriculo-arterial connections, levocardia
Aortic coarctation	+ Aortic coarctation
Tetralogy of Fallot	Normal atrial arrangement, concordant atrioventricular and ventriculo-arterial connections, levocardia
Tetralogy of Fallot	+ VSD with pulmonary stenosis, overriding aorta, right ventricular hypertrophy
Transposition of the great arteries with associated VSD	Normal atrial arrangement, concordant atrioventricular and discordant ventriculo-arterial connections, levocardia
Transposition of the great arteries with associated VSD	+ VSD
Congenitally corrected transposition of the great arteries	Normal atrial arrangement, discordant atrioventricular and discordant ventriculo-arterial connections, levocardia
Double-outlet right ventricle	Normal atrial arrangement, concordant atrioventricular and double-outlet ventriculo-arterial connections from the right ventricle, levocardia
Double-outlet right ventricle	+ VSD
Left isomerism	Ambiguous atrial arrangement, ambiguous atrioventricular and ambiguous ventriculo-arterial connections, levocardia
Left isomerism	+ Bilateral bilobed lungs with hyparterial bronchus on both sides, polysplenia, interrupted inferior vena cava with azygos continuation
