The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta. It is one of the four valves of the heart and one of the two semilunar valves, the other being the pulmonary valve. The aortic valve normally has three cusps or leaflets, although in 1–2% of the population it is found ...
The aortic and pulmonary valves are located at the base of the aorta and the pulmonary trunk respectively. These are also called the "semilunar valves". These two arteries receive blood from the ventricles and their semilunar valves permit blood to be forced into the arteries, and prevent backflow from the arteries into the ventricles.
Aortic valve replacement. ICD-9-CM. 35.21 - 35.22 V43.3. [edit on Wikidata] Aortic valve replacement is a cardiac surgery procedure whereby a failing aortic valve is replaced with an artificial heart valve. The aortic valve may need to be replaced because of aortic regurgitation (back flow), or if the valve is narrowed by stenosis.
Frequency. 2% of people over 65 (developed world) [1] Aortic stenosis (AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. [1] It may occur at the aortic valve as well as above and below this level. [1] It typically gets worse over time. [1]
The wave is reflected at sites of impedance mismatching, such as bifurcations, where reflected waves rebound to return to semilunar valves and the origin of the aorta. These return waves create the dicrotic notch displayed in the aortic pressure curve during the cardiac cycle as these reflected waves push on the aortic semilunar valve. [17]
Each atrioventricular valve (tricuspid and mitral valves) consists of the leaflets, the annulus, the tendinous cords, the papillary muscles, and the supporting muscle mass. Semilunar valves (pulmonary and aortic valves) consists of leaflets, the sinuses and the interleaflet triangles. [30]
