The valve that guards the left atrioventricular junction, traditionally called the mitral valve, may have different morphologies in the congenitally malformed heart. This valve may not have all the anatomic charecterystics of the mitral valve in many cases.
Image of the mitral valve viewed from the left atrium cropped in an attitudinally appropriate plane in anatomical view using the Tomtec MV assessment software. The leaflets of the mitral valve is automatically labelled as shown here. Dynamic image of the same patient is displayed below.
Bileaflet prolapse of the mitral valve.
Displayed below is a 3D echo of the mitral valve seen from the LA (surgeon's view). Aortic valve is shown in the 12'O clock position. Below it is the anterior leaflet of the mitral valve. Part of the right ventricle is seen in the right side. With the progress of ventricular systole, both the leaflet bulges in o the LA. The main foci of coaptation failure is between A3 and P3.

Video below is that of a patient with severe MR due to rheumatic heart disease. Severe coaptation failre between the anterior and posterior leaflets due to an immobile posterior leaflet is clearly visible.
