Heart Valves

« Back to Glossary Index

The heart has four valves that help regulate the flow of blood through the heart. The four valves are:

  1. The tricuspid valve, which is located between the right atrium and right ventricle
  2. The pulmonary valve, which is located between the right ventricle and the pulmonary artery
  3. The mitral valve, which is located between the left atrium and left ventricle
  4. The aortic valve, which is located between the left ventricle and the aorta

Heart Valves

The valves have flaps, called leaflets, that open and close to allow blood to flow in one direction through the heart. The valves ensure that blood flows in the correct direction and helps to prevent it from flowing backward.

Problems with the heart valves, such as stenosis (narrowing) or regurgitation (leakage), can cause symptoms such as shortness of breath, chest pain, and fatigue. These problems can be treated with medications, lifestyle changes, or surgery.
