The sinuses of Valsalva The sinuses of Valsalva are small dilatations in the aortic wall just above each of the three cusps of the aortic valve, between the aortic valve annulus and the sinotubular ridge. Aneurysms of these sinuses are thin-walled outpouchings that usually protrude into an adjacent cardiac chamber via either a direct connection or a “windsock” tract that extends from the aneurysm. When such aneurysms rupture, they form a fistulous connection with one of the chambers of the heart that usually produces symptoms.
