   en.wikipedia.org/wiki/Commissurotomy

   Illustration demonstrating an open-heart surgery to repair a mitral valve that is narrowed from mitral valve stenosis. [ edit on Wikidata ] A commissurotomy ( / ˌ k ɒ m ə ʃ ər ˈ ɒ t ə m i / ) is a surgical incision of a commissure in the body, as one made in the heart at the edges of the commissure formed by cardiac valves , or one made ...

   en.wikipedia.org/wiki/Mitral_valve

   The mitral valve is typically 4 to 6 square centimetres (0.62 to 0.93 sq in) in area and sits in the left heart between the left atrium and the left ventricle. [5] It has two cusps: an anterior one, and a posterior one. [6] The opening of the mitral valve is surrounded by a fibrous ring known as the mitral annulus. The anterior cusp attaches to ...

4. Commissure - Wikipedia

   en.wikipedia.org/wiki/Commissure

   A commissure (/ ˈ k ɒ m ə ʃ ər /) is the location at which two objects abut or are joined. The term is used especially in the fields of anatomy and biology. The most common usage of the term refers to the brain's commissures, of which there are at least nine. Such a commissure is a bundle of commissural fibers as a tract that crosses the midline at i

5. Mitral valve replacement - Wikipedia

   en.wikipedia.org/wiki/Mitral_valve_replacement

   Mitral valve replacement is a procedure whereby the diseased mitral valve of a patient's heart is replaced by either a mechanical or tissue (bioprosthetic) valve. The mitral valve may need to be replaced because: [citation needed] The valve is leaky (mitral valve regurgitation) The valve is narrowed and doesn't open properly (mitral valve ...

6. Mitral valve repair - Wikipedia

   en.wikipedia.org/wiki/Mitral_valve_repair

   Mitral valve repair is a cardiac surgery procedure performed by cardiac surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart.

7. Mitral stenosis - Wikipedia

   en.wikipedia.org/wiki/Mitral_stenosis

   The mitral valve opens when the pressure in the left atrium is greater than the pressure in the left ventricle. This happens in ventricular diastole (after closure of the aortic valve), when the pressure in the ventricle precipitously drops. In individuals with mitral stenosis, the pressure in the left atrium correlates with the severity of the ...
