Situs inversus may remain asymptomatic throughout
life, with little impact on cardiorespiratory function. Situs inversus is a
feature of Kartagener syndrome, asplenia syndrome, and polysplenia syndrome.
Clinical features of these medical conditions may therefore be present. Congenital heart
disease described with situs inversus includes ventricular septal defect,
atrial septal defect, transposition of the great arteries, and conotruncal
malformations.
