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 .

A valvulotomy, valvotomy, [1] valvuloplasty, or valvoplasty is a procedure used in heart valve surgery that consists of making one or more incisions at the edges of the commissure formed between the two (mitral valve), or three tricuspid valve leaflets. This relieves the constriction of valvular stenosis (especially mitral valve stenosis ...
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. [ 2 ]
During systole, the valve closes, which means blood has just one option—to be ejected out the aortic valve and into circulation. If the mitral valve doesn’t shut all the way, blood can leak back into the left atrium, called mitral valve regurgitation. During diastole, the mitral valve opens and lets blood fill into the ventricle.
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 ...
MitraClip (mitral clip) is a medical device used to treat mitral valve regurgitation for individuals who should not have open-heart surgery. It is implanted via a tri-axial transcatheter technique and involves suturing together the anterior and posterior mitral valve leaflets.
