Sample Solution

Aortic Stenosis/Regurgitation Aortic stenosis (AS) is the narrowing of the aortic valve, due primarily to a combination of progressive fibrosis and calcification of the matrix, with consequent increase in valve stiffness, progressive reductions in valve area and concomitant increases in left ventricular afterload and work. The most common cause of aortic stenosis is the accumulation of calcium deposits on the aortic valve, which increases with age. This causes the aortic valve to stiffen and narrow over time. Risk factors include older age, certain heart conditions present at birth (congenital heart disease) such as a biscupid aortic valve, and history of infections that can affect the heart.
