<unk>  (also called<unk> tus transversus) is a rare congenital condition in which the major visceral organs are reversed or mirrored from their normal positions. The normal arrangement is known as<unk> tus solitus. In other rare cases, in a condition known as<unk> tus ambiguus or heterotaxy,<unk> tus cannot be determined.
The term<unk>  is a short form of the Latin phrase<unk>  viscerum," meaning "inverted position of the internal organs."  Dextrocardia (the heart being located on the right<unk> de of the thorax) was first recognised by Marco Severino in 1643.  However,<unk>  was first described more than a century later by Matthew Baillie.
The prevalence of<unk>  varies among different populations but is less than 1 in 10,000 people.
