Dextroposition of the heart: The heart is displaced to the right (from its usual location in the left chest). There is no anatomic alteration in the heart itself, just in its location. 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 chest are reduced (for example, by collapse of the right lung) and the heart moves toward the sparsely occupied space on the right.
