Dextrocardia

Dextrocardia
The heart is reversed and is in the right side of the chest rather than in its normal location on the left. This is a true anatomic reversal. With dextrocardia, for example, the apex (tip) of the heart points to the right rather than (as is normal) to the left. Dextrocardia occurs in an abnormal condition present at birth (congenital) called Kartagener’s syndrome.

n.
a congenital defect in which the position of the heart is a mirror image of its normal position, with the apex of the ventricles pointing to the right. It may be associated with other congenital defects and is often combined with situs invertus, in which the appendix and liver lie on the left side of the abdomen and the stomach lies on the right side. Isolated dextrocardia produces no adverse effects.
