- The heart is reversed and is in the right side of the chest rather than in its normal location on the left. This is a true anatomic reversal. With dextrocardia, for example, the apex (tip) of the heart points to the right rather than (as is normal) to the left. Dextrocardia occurs in an abnormal condition present at birth (congenital) called Kartageners syndrome.
* * *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. SYN: dexiocardia. [dextro- + G. kardia, heart]- corrected d. displacement and rotation of the heart into the right side of the chest but without mirror transposition of the cardiac chambers. SYN: dextroversion of the heart, false d., type 3 d..- false d. SYN: corrected d..- isolated d. d. with mirror-image transposition of the cardiac chambers but without displacement of the abdominal viscera. SYN: type 2 d..- mirror image d. perfect right to left congenital reversal of the heart sometimes with other congenital abnormalities, sometimes normal except for position.- secondary d. dextroposition of the heart by some disease of the lungs, pleura, or diaphragm. SYN: type 4 d..- type 2 d. SYN: isolated d..- type 3 d. SYN: corrected d..- type 4 d. SYN: secondary d..- d. with situs inversus displacement of the heart to the right side of the chest with mirror-image transposition of the cardiac chambers together with transposition of the abdominal viscera. SYN: type 1 d..

* * *n.a congenital defect in which the position of the heart is a mirror image of its normal position, with the apex of the ventricles pointing to the right. It may be associated with other congenital defects and is often combined with situs invertus, in which the appendix and liver lie on the left side of the abdomen and the stomach lies on the right side. Isolated dextrocardia produces no adverse effects.
* * *dex·tro·car·dia (dek″stro-kahrґde-ə) [dextro- + cardia] location of the heart in the right hemithorax, with the apex pointing to the right, occurring with transposition (situs inversus) of the abdominal viscera, or without such transposition.
