Situs inversus 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. Many people with situs inversus have no medical symptoms resulting from the condition, although cardiac problems are the most common complication. Until the advent of modern medicine, it was usually undiagnosed.
