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.
