Aortic valve

An aortic sinus is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve.
The three cusps, when the valve is closed, contain a sinus called an aortic sinus or sinus of Valsalva.

Right coronary artery

The anterior aortic sinus gives rise to the right coronary artery.
In the coronary circulation, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart.

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

ALCAPABland–White–Garland syndrome
Anomalous left coronary artery from the pulmonary artery (ALCAPA or Bland-White-Garland syndrome or White-Garland syndrome) is a rare congenital anomaly in which the left coronary artery (LCA) branches off the pulmonary artery instead of the aortic sinus.

Baroreceptors are stretch receptors located in the aortic sinus, carotid bodies, the venae cavae, and other locations, including pulmonary vessels and the right side of the heart itself.

Cardiovascular centre

cardiovascular center
When a change of blood pH is detected by central chemoreceptors or by peripheral chemoreceptors in aortic bodies and in carotid bodies, or a change of blood pressure is detected by baroreceptors in the aortic sinuses or carotid sinuses, the cardiovascular centre affects changes to the heart rate by sending a nerve impulse to the cardiac pacemaker (or SA node) via sympathetic fibres (to cause faster and stronger cardiac muscle contraction) and the vagus nerve (to cause slower and less strong cardiac muscle contraction).

Arterial switch operation

arterial switchJatene operation
The coronary ostia and a large "button" of surrounding aortic wall are then excised from the aorta, well into the sinus of Valsalva; and the proximal sections of the coronary arteries are separated from the surface of the heart, which prevents tension or distortion after anastomosis to the neo-aorta.
