dextrocardia (redirected from isolated dextrocardia)

dextrocardia /dex·tro·car·dia/ (-kahr´de-ah) location of the heart in the right side of the thorax, the apex pointing to the right.

isolated dextrocardia  mirror-image transposition of the heart without accompanying alteration of the abdominal viscera.

mirror-image dextrocardia  location of the heart in the right side of the chest, the atria being transposed and the right ventricle lying anteriorly and left of the left ventricle.

dex·tro·car·di·a (dkstr-kärd-)

n.

The displacement of the heart to the right, either as dextroposition of a normal heart, or as cardiac heterotaxia, in which the left and right chambers are transposed.

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. Cf Kartagener's syndrome. Cf Dextroposition of the heart.
