- Situs solitus refers to normal visceroatrial situs, situs inversus is a fully inverted visceroatrial situs, and situs ambigus is defined as a situs that does not correspond to either of the two previous categories. - Visceroatrial situs depends on the abdominal, the pulmonary and the atrial situs. - Abdominal situs is only dictated by the position of the liver, the stomach and the spleen. - The position of the heart and the great vessels should not be considered during assessment of visceroatrial situs. - Several conditions are associated with situs inversus and visceroatrial isomerism, including congenital heart diseases and primary ciliary dyskinesia. - Visceroatrial situs abnormalities should be systematically sought in cases of dextrocardia, asplenia, polysplenia, primary ciliary dyskinesia, atrioventricular septal defects and in case of anomalous pulmonary/systemic venous return.
