Mitral valve agenesis is very rare, defined as an absence or minimal presence of both mitral valve leaflets (complete agenesis) or one of the leaflets (partial agenesis). [16] Surgery can be performed to replace or repair a damaged valve. A less invasive method is that of mitral valvuloplasty which uses a balloon catheter to open up a stenotic ...
The mitral valve is also called the bicuspid valve because it contains two leaflets or cusps. The mitral valve gets its name from the resemblance to a bishop 's mitre (a type of hat). It is on the left side of the heart and allows the blood to flow from the left atrium into the left ventricle .
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The mitral valve has two leaflets—the anterior and posterior leaflet, and together they separate the left atrium from the left ventricle. During systole, the valve closes, which means blood has just one option—to be ejected out the aortic valve and into circulation.
The valve leaflets are separated by two commissures, and each leaflet of the valve (anterior leaflet, the large one, and posterior leaflet, the small one) has three sections (p1, p2, p3). Histologically, each leaflet is composed of the solid fibrosa, the spongiosa at the atrial surface and another fibroelastic layer covering the leaflets. [ 1 ]
The mitral valve and tricuspid valve are formed by the proper division of an early common valve being separated into two. [5] Atrioventricular canal defect may be divided into partial or complete forms. In the partial form, openings between the left and right atria and improper formation of the mitral valve exist.
The device fastens together the mitral valve leaflets to improve the heart's blood outflow. The mitral clip has not yet established the same long-term reliability as septal myectomy or alcohol septal ablation, but HCM specialists are increasingly offering the clip as a less-invasive treatment option.

An echocardiogram is the most common and specific way to diagnose Ebstein’s anomaly because it effectively shows all 4 chambers of the heart, which displays the distance between the hinge point of the septal leaflet of the tricuspid valve and the anterior leaflet of the mitral valved (displacement index) to determine if the value is greater ...
