2. Aortic valve replacement - Wikipedia

   The aortic valve is opened during systole, the driving force for it to open is the difference in pressure between the contracting left ventricle of the heart and the aorta. During cardiac diastole (when the heart chamber gets bigger) the aortic valve closes. [5] Aortic stenosis most commonly is the result of calcification of the cusps.

   Common features of both techniques of the replacement process are the clamping of the aorta and the use of a length of Dacron tube (also known as an "aortic graft"), typically 5 cm, to constrict the aortic root to the normal diameter, while the patient is cooled to 20°C and placed on life support. The procedure typically takes 4 to 6 hours in ...

6. Aortic stenosis - Wikipedia

   en.wikipedia.org/wiki/Aortic_stenosis

   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] Symptoms often come on gradually with a decreased ability to exercise often ...
