1. Situs inversus

   Situs inversus (also called situs transversus or oppositus) is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. The normal arrangement of internal organs is known as situs solitus. Although cardiac problems are more common, many people with situs inversus have no medical symptoms or complications resulting from the condition, and until the advent of modern medicine, it was usually undiagnosed. Situs inversus is found in about 0.01% of the population, or about 1 person in 10,000. In the most common situation, situs inversus totalis, it involves complete transposition (right to left reversal) of all of the viscera. The heart is not in its usual position in the left chest, but is on the right, a condition known as dextrocardia (literally, "right-hearted"). Because the relationship between the organs is not changed, most people with situs inversus have no associated medical symptoms or complications.An uncommon form of situs inversus is isolated levocardia, in which the position of the heart is not mirrored alongside the other organs. Isolated levocardia carries a risk of heart defects, and so patients with the condition may require surgery to correct them. In rarer cases such as situs ambiguus or heterotaxy, situs cannot be determined. In these patients, the liver may be midline, the spleen absent or multiple, and the bowel malrotated. Often, structures are duplicated or absent altogether. This is more likely to cause medical problems than situs inversus totalis.

1. Situs inversus

   Situs inversus is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. The normal arrangement is known as situs solitus. In other rare cases, in a condition known as situs ambiguus or heterotaxy, situs cannot be determined. The term situs inversus is a short form of the Latin phrase "situs inversus viscerum", meaning "inverted position of the internal organs". Dextrocardia was first seen and drawn by Leonardo da Vinci in 1452–1519, and then recognised by Marco Aurelio Severino in 1643. However, situs inversus was first described more than a century later by Matthew Baillie. The prevalence of situs inversus varies among different populations but is less than 1 in 10,000 people.

1. Situs Inversus

   A congenital abnormality in which organs in the THORAX and the ABDOMEN are opposite to their normal positions (situs solitus) due to lateral transposition. Normally the STOMACH and SPLEEN are on the left, LIVER on the right, the three-lobed right lung is on the right, and the two-lobed left lung on the left. Situs inversus has a familial pattern and has been associated with a number of genes related to microtubule-associated proteins.
