[‚dek·strō′kär·dē·ə] (medicine) 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).

dextrocardia

A heart misplaced in the right chest, with the apex of the heart pointing right; the cardiac function is normal if there is concomitant situs inversus of the abdominal organs–mirror-image dextrocardia; if the dextrocardia is due to immotile cilia, sinusitis and bronchiectasis–Kartagener syndrome may also be present EKG Mirror-image electrical activity with P, QRS, and T waves in leads I, aVR, aVL that are the reverse of the normal; the right activity resembles that normally seen in the left side of the chest; if the abdominal organs are not reversed, dextrocardia may be associated with ventricular inversion, single-chamber ventricle, pulmonary valve stenosis and anomalies of venous return. See Kartagener's syndrome. Cf Dextroposition of the heart.

dex·tro·car·di·a

(deks'trō-kahr'dē-ă) Displacement of the heart to the right, either as dextroposition, with simple displacement to the right, or as cardiac heterotaxia, with complete transposition of the right and left chambers, resulting in a heart that is the mirror image of a normal heart.
