The hiatus is situated slightly to the left of the midline and is bounded anteriorly by the crura and the median arcuate ligament that connects them, and posteriorly by L1.
A number of structures pass through the aortic hiatus:
The vertebral levels of the 3 main diaphragmatic apertures can be remembered by this mnemonic.
