ANATOMY

Detailed explanation-1: -The aortic valve doesn’t close properly, causing blood to flow backward into the left lower heart chamber (ventricle).

Detailed explanation-2: -An untreated bicuspid aortic valve can eventually lead to symptoms of heart failure. These include shortness of breath, fatigue, and swelling. Also, an aortic aneurysm might develop downstream from the aortic valve and can lead to bleeding or rupture.

Detailed explanation-3: -The valve allows blood to flow from the left ventricle (pumping chamber) to the aorta and prevents blood from flowing backward.

Detailed explanation-4: -Oxygen-rich blood returns to the left atrium via the pulmonary veins. Blood flows from the right atrium into the right ventricle through the bicuspid valve. From the left ventricle, blood is pumped into the aorta, through the aortic semilunar valve.

Detailed explanation-5: -A bicuspid aortic valve has two flaps, called cusps, instead of three. It can cause the valve opening to become narrowed or blocked. When this happens, the condition is called aortic valve stenosis. The heart has to work harder to pump blood into the body’s main artery, called the aorta.
