WebAortic stenosis is a type of valvular heart disease that obstructs the flow of blood out of the heart. Advanced aortic stenosis causes significant symptoms, and greatly reduces life … WebThe pressure within the aorta and arterial system is called the after load. To eject blood, the heart develops pressure equal to or greater than the after load. Hydrostatic pressure is that which is exerted on the walls of the vessel by the fluid within the vessel. The rapid ejection of blood into the aorta can be felt as a pulse (pressure wave).
