Is Heart Valve Disease?

Heart valve disease occurs when the heart valves do not work the way they should.

How Does Heart Valve?

Your heart valves lie at the exit of each of your four heart chambers and maintain one-way flow of blood through your heart. The four heart valves ensure that blood always flows freely in a forward direction and that there is no backward leakage.

Blood flows from the right and the left atrium into the ventricle via the mitral and tricuspid valves open.

When the full ventricle, tricuspid and mitral valve is closed. This prevents the blood to flow backwards into the atria while the ventricles contract (squeeze).

When the ventricles begin to contract, pulmonary and aortic valves are forced open and blood is pumped out of the ventricle through the open valve into the pulmonary artery toward the lungs, aorta, and the body.

When the ventricles finish contracting and begin to relax, the aortic and pulmonary valves close. This valve prevents blood flowing back into the ventricle.

This pattern is repeated, causing the blood continues to flow to the heart, lungs, and body.
