Mitral valve of blood through the valve. The word "mitral" comes from Latin, meaning "shaped like a mitre" (bishop's hat). The word "bicuspid" uses combining forms of "bi-", from Latin, meaning "double", and "cusp", meaning "point", reflecting the dual-flap shape of the valve. Mitral valve The mitral valve (), also known as the bicuspid valve or left atrioventricular valve, is a valve with two flaps 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
Mitral valve repair left atrium or lungs when the ventricle contracts (squeezes) to push blood out to the body. It has two flaps, or leaflets, known as cusps. The techniques of mitral valve repair include inserting a cloth-covered ring around the valve to bring the leaflets into contact with each other (annuloplasty), removal of redundant/loose segments of the leaflets (quadrangular resection), and re-suspension of the leaflets with artificial (Gore-Tex) cords. Procedures on the mitral valve usually require a median sternotomy, but advances in non-invasive methods (such as keyhole surgery) allow surgery without a sternotomy (and resulting pain and scar).
