Rheumatic heart disease often involves valves

Rheumatic heart disease often involves the mitral valve, aortic valve, tricuspid valve, etc.

1. Mitral

valve is the left atrioventricular valve. When the heart contracts, the pressure on the left heart is large, and it is also prone to damage. Therefore, when rheumatic heat invades the heart, it is easy to affect the mitral valve.

2. Aortic valve

Aortic valve is located between the left ventricle and the aorta. Because it is in the middle of the heart, it is closely related to each heart chamber and vascular valve, so rheumatic heat can also affect the aortic valve.

3. Tricuspid

valve is the right atrioventricular valve. When the heart contracts, the tricuspid valve opens, so that systemic blood flows into the lungs for oxygenation. Rheumatic heat invasion may also damage the tricuspid valve. However, due to the low pressure on the right ventricle, compared with the above two valves, the probability of invasion is small.
