The mitral valve is a crucial component of the heart, located between the left atrium and the left ventricle. It has two flaps, or leaflets, that open and close to regulate blood flow. When the heart beats, the valve opens to allow oxygen-rich blood to flow from the atrium into the ventricle, and then it closes to prevent backflow when the ventricle contracts. Proper functioning of the mitral valve is essential for maintaining efficient circulation. If the valve becomes damaged or diseased, it can lead to conditions such as mitral valve prolapse or mitral regurgitation, which may require medical intervention to restore normal heart function.
