Mitral Valve

« Back to Glossary Index

The mitral valve is one of the four valves in the human heart, situated between the left atrium and the left ventricle. It plays a crucial role in regulating the blood flow within the heart. Also known as the bicuspid valve due to its two leaflets, the mitral valve ensures the unidirectional flow of oxygenated blood from the left atrium into the left ventricle while preventing backflow.

This valve opens during the heart’s relaxation phase (diastole) to allow blood to fill the left ventricle, and it closes during the contraction phase (systole) to prevent the reverse flow into the atrium. Malfunctions or diseases affecting the mitral valve, such as mitral valve regurgitation or stenosis, can lead to impaired cardiac function and may require medical intervention, including surgical repair or replacement. Regular monitoring and appropriate medical care are essential to maintain the optimal functioning of the mitral valve and overall cardiovascular health.
