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 stenosis individuals with a crisp opening snap, score < 8, and no calcium in the commissures. Treatment also focuses on concomitant conditions often seen in mitral stenosis: Mitral valvuloplasty is a minimally invasive therapeutic procedure to correct an uncomplicated mitral stenosis by dilating the valve using a balloon. Under local anaesthetic, a catheter with a special balloon is passed from the right femoral vein, up the inferior vena cava and into the right atrium. The interatrial septum is punctured and the catheter passed into the left atrium using a "trans-septal technique." The balloon is sub-divided into 3 segments and is dilated
