aortic sinus

The anterior aortic sinus gives rise to the right coronary artery.

The posterior aortic sinus does not give rise to a coronary artery.

No artery arises from the posterior aortic sinus.

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

Usually, no vessels arise from the right posterior aortic sinus, which is therefore known as the non-coronary sinus.

Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is comparatively rare.

Medical therapy of aneurysm of the aortic sinus includes blood pressure control through the use of drugs, such as beta blockers.

Petit's sinuses: Also known as aortic sinuses, the space between each semilunar valve and the wall of the aorta.

When blood pressure rises, the carotid and aortic sinuses are distended, resulting in stretch and, therefore, activation of the baroreceptors.

For this reason, the left, right and posterior aortic sinuses are also called left-coronary, right-coronary and non-coronary sinuses.

The sinotubular junction is the point in the ascending aorta where the aortic sinuses end and the aorta becomes a tubular structure.

Aortic sinus ("sinus of Morgagni")

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

An aneurysm of the aortic sinus may rupture due to infective endocarditis involving the aortic wall and tertiary-stage syphilis.

He coined the term Eustachian tube and he described the aortic sinuses of Valsalva in his writings, published posthumously in 1740.

Between each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses.

Fainting can occur but usually baroreceptors within the aortic sinuses initiate a baroreflex such angiotensin II and norepinephrine stimulate vasoconstriction and heart rate increases to return blood flow.

The left coronary artery originates from the left aortic sinus, while the right coronary artery originates from the right aortic sinus.

The only branches of the ascending aorta are the two coronary arteries which supply the heart; they arise near the commencement of the aorta from the aortic sinuses which are opposite the aortic valve.

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.

At the root of the ascending aorta, the lumen has three little pockets between the cusps of the aortic valve and the wall of the aorta, named the aortic sinuses or sinuses of Valsalva.
