Overview
The aortic sinus is a section of the ascending aorta that is normally dilated (enlarged or widened) just above the aortic valve.
There are generally three aortic sinuses, the left, the right and the posterior.
- 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.
Shown below is a drawing depicting the aortic sinus anatomy. Note that the aortic sinus has three cusps: the left coronary cusp, the right coronary cusp and the non coronary cusp.
