Aortic valve. 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 ...
Heyde's syndrome is a syndrome of gastrointestinal bleeding from angiodysplasia in the presence of aortic stenosis. [ 1][ 2] It is named after Edward C. Heyde, MD, who first noted the association in 1958. [ 3] It is caused by cleavage of Von Willebrand factor (vWF) due to high shear stress forces from aortic valvular 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]
