The aortic valve plays a crucial role in effective blood circulation. It is located between the body’s main artery (aorta) and the heart’s left ventricle. When the ventricle contracts, the valve opens to allow blood to move into the aorta and through to the rest of the body. However, when this valve is damaged, the body’s entire circulatory system can suffer. Of the problems that may affect the aortic valve, aortic stenosis is the most common.
