A condition in which the heart is located in the right side of the chest, instead of the left. Or, in more technical terms, an anomaly in which the primitive heart tube folds to the left in a mirror image of a normal bulboventricular loop, resulting in the heart being located in the right hemithorax. This is often associated with situs inversus, a condition in which the positions of other interior organs are also reversed from the norm.

Dextrocardia may be associated with high rates of congenital heart disease, although when accompanied by situs inversus this risk decreases.

Dextrocardia can be caused by an autosomal recessive gene, or may appear in one of a set of identical twins in the case of mirror twins.
