The presence of the heart in the right hemithorax, with the cardiac apex directed to the right.

Dextrocardia

 

a congenital anomaly of the position of the heart in which most of the heart is located in the right hemithorax. It is usually associated with transposition of all viscera. It is most often discovered by chance during X-ray or electrocardiographic examinations. Dextrocardia should not be confused with dextroposition of the heart, which is a shift of the heart to the right in cases of diseases of the neighboring organs (accumulation of fluid in the left pleural cavity, shrinkage or collapse of the right lung, and so on).
