Heterotaxy (or heterotaxy syndrome) is a condition in which the organs of the chest and abdomen are abnormally located, usually on opposite sides from their usual places. This typically affects the heart, lungs, liver, spleen and intestines.

Sometimes, the rearrangement is harmless. However, when the attachment of the large blood vessels, especially to the heart, are involved, the condition is life-threatening.

Heterotaxy syndrome can cause the skin to appear bluish (cyanosis), due to a shortage of oxygen. It can cause breathing difficulties, an increased risk of infections, biliary atresia (a liver problem), and digestion problems.
