Overview

Cardiomegaly must be distinguished from pseudo-cardiomegaly, a scenario in which the apparent size of the heart is artificially increased. Disorders and conditions which falsely increase the apparent size of the heart include straight back syndrome, a disorder in which the heart is "pancaked" or compressed; and obtaining the chest x-ray during expiration at which time the diameter of the lungs is decreased and the relative diameter of the heart and aorta is increased.
