Dextrocardia (from Latin dextro, meaning "right hand side," and Greek kardia, meaning "heart") is a rare congenital condition in which the apex of the heart is located on the right side of the body, rather than the more typical placement towards the left. There are two main types of dextrocardia:  dextrocardia of embryonic arrest (also known as isolated dextrocardia) and dextrocardia situs inversus. Dextrocardia situs inversus is further divided. Classification
Dextrocardia of embryonic arrest
In this form of dextrocardia, the heart is simply placed further right in the thorax than is normal. It is commonly associated with severe defects of the heart and related abnormalities including pulmonary hypoplasia. Dextrocardia situs solitus
Dextrocardia refers to a heart positioned in the right side of the chest. Situs solitus describes viscera that are in the normal position, with the stomach on the left side. Dextrocardia situs inversus
Dextrocardia situs inversus refers to the heart being a mirror image situated on the right side. For all visceral organs to be mirrored, the correct term is dextrocardia situs inversus totalis.Although statistically people with dextrocardia do not have any medical problems from the disorder, they may be prone to a number of bowel, esophageal, bronchial and cardiovascular disorders (such as double outlet right ventricle, endocardial cushion defect and pulmonary stenosis). Certain cardiovascular and pulmonary disorders related to dextrocardia can be life-threatening if left unchecked.Kartagener syndrome may also be present in patients with dextrocardia but this must be in the setting of situs inversus and may include male infertility.
