During early heart development, the linear heart tube must reorganize to form the four-chamber heart. It does this by looping toward the right (dextral looping) and bending forward (anteriorly). This anterior/rightward looping sets up the correct spatial arrangement of the chambers and the outflow tracts, so the apex ultimately points toward the left side of the chest. Recognizing that normal looping is anterior and rightward helps explain the normal fetal heart orientation seen on imaging; deviations from this pattern can lead to congenital malformations.
