Which description best defines mesocardia?

Mesocardia describes a heart that sits in the midline of the chest with the apex directed toward the inferior aspect, downward toward the diaphragm. In fetal imaging, you’d see the cardiac silhouette centered between the lungs and the apex pointing downward rather than toward the left or right. This distinguishes it from levocardia, where the heart is mainly on the left with the apex pointing left, and dextrocardia, where the heart is on the right with the apex pointing right. The midline position with an inferior-pointing apex is the defining feature, which is why this description best fits mesocardia.
