Aortic sinuses

Anatomy of the aortic valvar complex

An aortic sinus, also called the sinuses of Valsalva is one of the anatomic dilatations 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.
