Anatomical terminology []

An aortic sinus is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve. These widenings are between the wall of the aorta and each of the three cusps of the aortic valve.

There are generally three aortic sinuses:(one anterior and 2 posterior sinuses):

Each aortic sinus can also be referred to as the sinus of Valsalva, the sinus of Morgagni, the sinus of Mehta, the sinus of Otto, or Petit's sinus.
