Aortic stenosis

The normal, human heart has four chambers: the right and left atria, and the right and left ventricles.

​The heart is in fact a bloodpump and has  four valves: the mitral valve, the tricuspid valve, the aortic valve and the pulmonary valve. The valves regulates blood flow by opening and closing during the heartbeat. If a valve is diseased, it might not fully open known as stenosis or might not fully close which allows for leaking known as regurgitation..

The aortic valve is the  valve oxygen-rich blood passes through before entering the aorta, the largest blood vessel in the human body. One of the most common and serious valvular heart diseases is called aortic stenosis. This is a condition where the aortic valve is thickened and calcified.The valve is narrowed and the left ventricle has to increase its struggle to pump the blood into the arteries. There are several complications linked to aortic stenosis such as abnormal heart musculature, heart failure and heart attack.
