1. Mitral valve

   The mitral valve (), also known as the bicuspid valve or left atrioventricular valve, is one of the four heart valves. It has two cusps or flaps and lies between the left atrium and the left ventricle of the heart. The heart valves are all one-way valves allowing blood flow in just one direction. The mitral valve and the tricuspid valve are known as the atrioventricular valves because they lie between the atria and the ventricles.In normal conditions, blood flows through an open mitral valve during diastole with contraction of the left atrium, and the mitral valve closes during systole with contraction of the left ventricle. The valve opens and closes because of pressure differences, opening when there is greater pressure in the left atrium than ventricle and closing when there is greater pressure in the left ventricle than atrium.In abnormal conditions, blood may flow backward through the valve (mitral regurgitation) or the mitral valve may be narrowed (mitral stenosis). Rheumatic heart disease often affects the mitral valve; the valve may also prolapse with age and be affected by infective endocarditis. The mitral valve is named after the mitre of a bishop, which resembles its flaps.

1. mitral valve

   The mitral valve is one of four valves in the heart that help direct the flow of blood. Specifically, it is located between the left atrium and left ventricle and ensures that blood flows in the correct direction, preventing it from flowing backwards into the left atrium when the left ventricle contracts. It is named for its resemblance to a bishop's mitre (a type of hat), and is also known as the bicuspid valve due to its two flaps or 'cusps'.

1. Mitral valve

   The mitral valve is a dual-flap valve in the heart that lies between the left atrium and the left ventricle. The mitral valve and the tricuspid valve are known collectively as the atrioventricular valves because they lie between the atria and the ventricles of the heart and control the flow of blood. During diastole, a normally-functioning mitral valve opens as a result of increased pressure from the left atrium as it fills with blood. As atrial pressure increases above that of the left ventricle, the mitral valve opens. Opening facilitates the passive flow of blood into the left ventricle. Diastole ends with atrial contraction, which ejects the final 20% of blood that is transferred from the left atrium to the left ventricle. This amount of blood is known as end diastolic volume, and the mitral valve closes at the end of atrial contraction to prevent a reversal of blood flow.
