As we mentioned in the previous articles, heart diseases are caused by high blood pressure that contributes to the hardening of the arteries. High levels of bad cholesterol (LDL) build up in the arteries as a result of uncontrolled diet with high levels of saturated fat and trans fat.

Heart diseases affecting heart valves occur when the mitral valve in the heart narrows, causing the heart to work harder to pump blood from the left atrium into the ventricle.

Here are some types of heart disease affecting heart valves:
1. Mitral Stenosis
Mitral Stenosis is a heart valve disorder that involves a narrowing or blockage of the opening of the mitral valve causing the volume and pressure of blood in the left atrium increases.

2. Mitral valves regurgitation
Mitral regurgitation is the heart disease in which your heart's mitral valve doesn't close tightly causing the blood to be unable to move through the heart efficiently. Symptoms of mitral valve regurgitation are fatigue and shortness of breath.

3. Mitral valves prolapse
In mitral valve prolapse, one or both leaflets of the valve are too large resulting in uneven closure of the valve during each heartbeat. Symptoms of mitral valves prolapse are palpitation, shortness of breath, dizzy, fatigue and chest pains.

4. Aortic Stenosis
With aging, protein collagen of the valve leaflets are destroyed and calcium is deposited on the leaflets causing scarring, thickening, and stenosis of the valve therefore increasing the wear and tear on the valve leaflets resulting in the symptoms and heart problems of aortic stenosis.

5. Aortic regurgitation
Aortic regurgitation is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. Symptoms of aortic regurgitation include fatigue or weakness, shortness of breath, chest pain, palpitation and irregular heart beats.

6. Tricuspid stenosis
Tricuspid stenosis is the narrowing of the orifice of the tricuspid valve of the heart causing increased resistance to blood flow through the valve. Symptoms of tricuspid stenosis include fatigue, enlarged liver, abdominal swelling, neck discomfort and leg and ankle swelling.

7. Tricuspid regurgitation.
Tricuspid regurgitation is the failure of the right ventricular causing blood to leak back through the tricuspid valve from the right ventricle into the right atrium of the heart. Symptoms of tricuspid regurgitation include leg and ankle swelling and swelling in the abdomen.
