An aortic sinus is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve.

There are generally three aortic sinuses: the left, the right and the posterior sinuses:

  • The left aortic sinus gives rise to the left coronary artery.
  • The right aortic sinus gives rise to the right coronary artery.
  • Usually, no vessels arise from the posterior aortic sinus, which is therefore known as the non-coronary sinus.

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.
