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
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
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.
