dextroposition of the heart

dextroposition of the heart A condition in which the heart is displaced to the right side of the chest, but without any anatomic alteration in the heart itself. Dextroposition occurs when the contents of the left side of the chest shove the heart to the right, or when the contents of the right side of the chest are reduced (for example, by collapse of the right lung) and the heart moves toward the sparsely occupied space on the right. See also dextrocardia.
