 Situs inversus - Encyclopedia, History, Geography and Biography   (Site not responding. Last check: 2007-10-18)
Situs inversus (also called situs transversus) is a rare congenital disorder in which the major visceral organs are reversed from left to right as a mirror image of the normal condition (which is known as situs solitus).
Situs inversus is an autosomal recessive genetic condition, but in many cases is confused with a mislabelled chest X-ray.
It is characterized by the triad of situs inversus, chronic sinusitis, and bronchiectasis.

 eMedicine - Situs Inversus : Article Excerpt by: Annamaria Wilhelm, MD
Situs solitus is the normal position, and situs inversus is the mirror image of situs solitus (see Image 1).
Situs inversus with dextrocardia also is termed situs inversus totalis because the cardiac position, as well as the atrial chambers and abdominal viscera, is a mirror image of the normal anatomy.
The features of situs ambiguous are inconsistent; therefore, situs ambiguous cases are challenging and require thorough evaluation of the viscera.

One unique form of dextroversion is termed the Cantrell syndrome, in which five components are present: midline epigastric abdominal wall defect often associated with herniation or omphalocele, a defect of the lower sternum, deficiency of the anterior diaphragm, defect of the diaphragmatic portion of the parietal pericardium, and diverticulum of the left ventricle.
The type of situs resulting in levocardia resemble those of dextrocardia, tow being associated with situs solitus, one with situs inversus, and two with situs ambiguous.
Levoversion of situs inversus represents the opposite of dextroversion of situs solitus.

A study was made of 19 adults with situs anomalies (situs inversus [n = 10], situs ambiguous with polysplenia [n — S], situs ambiguous with asplenia [n = 1]).
The eight adults with situs ambiguous with polysplenia demonstrated a spectrum of abnormalities.
Recognition of the spectrum of situs anomalies is important because the altered anatomy associated with these anomalies may result in confusing imaging findings when seen in conjunction with acquired diseases.

 Atrioventricular
Situs solitus indicates the usual or normal pattern, situs inversus the mirror-image of the normal pattern, and situs ambiguous denotes an ambiguous or indeterminate pattern.
The situs of the atrioventricular connection is based on the relationships of the atria to the ventricles, and is derived from the ventricular looping pattern.
For example, in venoatrial situs solitus and a D-looped ventricle, {S,D,-}, the morphologically right venoatrial connection is normal and right-sided, and the morphologically right ventricular valve is also right-sided, hence atrioventricular concordance is present.

Instead, responding to the arguments that admiralty jurisdiction was limited to commercial maritime activity, the Court found that the tort's "significant connection with traditional maritime activity" and the accident's "potential disruptive impact" on maritime commerce prompted an exercise of federal jurisdiction.
In addition to examining situs, Foremost required federal courts to ask whether the tort bore a significant relationship to maritime commerce, and whether the accident had a potential disruptive impact on maritime commerce.
As the majority quite ably demonstrates, the situs requirement is satisfied because the tort was caused by a "spud barge" on the Chicago River.
