Mitral valve leaflets

Mitral valve leaflets

The mitral valve is made up of two valve leaflets (the anteromedial leaflet and the posterolateral leaflet) and a ring around the valve, known as the mitral valve annulus. The orientation of the two leaflets resembles a bishop's miter, which is where the valve receives its name.

DMV disease is the most common reason mitral valve leaflets become floppy (prolapsed), causing the valve to leak.
The mitral valve leaflets were thickened with flail anterior segments (A1 andA2), hence neochordae were constructed for these segments in addition to ring annuloplasty using Sorin Memo 3D annuloplasty ring No.
Mitral regurgitation was diagnosed by the presence of thickened valves, dilated mitral valve annuli, and left atrial and left ventricular dilatation, and lack of coaptation of the mitral valve leaflets in systole.
Several long-term prognostic studies suggest that complications occur most commonly in patients with a mitral systolic murmur, those with thickened redundant mitral valve leaflets, and those with increased left ventricular or left atrial size, especially in men older than 45 years.
MR is a vastly underserved condition in which the mitral valve leaflets fail to close properly, allowing backflow of blood from the left ventricle into the left atrium during systole.
Mitral regurgitation [MR] is a condition in which the heart's mitral valve leaflets do not close tightly.
1,2 The procedure is technically successful in over 90% patients, and the long-term durability of commissurotomy is excellent in those with pliable mitral valve leaflets and minimally deformed submitral apparatus.
Multiple studies in animal mitral valve tissue showed mitral valve leaflets are stretchable tissue: anterior leaflet experienced large, anisotropic and stretched during closure.
When the left ventricle contracts, the mitral valve leaflets bulge (prolapse).
The structure of left atrioventricular valve apparatus is composed by the mitral annulus, mitral valve leaflets, chordae tendineae and papillary muscles and has been studied elsewhere (Silverman & Hurst, 1968; Lam et al.
The repair uses a small, metal, fabric-coated clip that attaches to two mitral valve leaflets and holds them together.
In mitral valve prolapse (also called Click-Murmur Syndrome, Barlow's Syndrome, Balloon Mitral Valve and Floppy Valve Syndrome), one or both mitral valve leaflets are enlarged or their supporting strings are too long.
