Aortic valve
The aortic valve separates the lower left chamber (left ventricle) of the heart and the aorta, the large artery that carries blood from the heart to the rest of the body. The aortic valve works like a one-way gate, opening so that blood from the left ventricle—the heart's main pump—can be pushed into the aorta. When the...
Aortic valve

Aortic valve regurgitation
Aortic valve regurgitation is the backflow of blood from the aorta through the aortic valve into the left ventricle. If enough blood flows back into the heart, it can increase the workload on the left ventricle (lower left chamber), causing damage. When the heart pumps, the aortic valve opens to let oxygen-rich blood...
