  2. Mitral stenosis - Wikipedia

    en.wikipedia.org/wiki/Mitral_stenosis

    Once symptoms of mitral stenosis begin to develop, progression to severe disability takes 9.2 ± 4.3 years. [citation needed] In individuals having been offered mitral valve surgery but refused, survival with medical therapy alone was 44 ± 6% at 5 years, and 32 ± 8% at 10 years after they were offered correction. [4]

  3. Mitral annular calcification - Wikipedia

    en.wikipedia.org/wiki/Mitral_annular_calcification

    Mitral annular calcification (MAC) is a multifactorial chronic degenerative process in which calcium with lipid is deposited in the annular fibrosa ring of the heart's mitral valve. MAC was first discovered and described in 1908 by M. Bonninger in the journal Deutsche Medizinische Wochenschrift. [1]

    This test can also show leaflet calcification and the pressure gradient over the mitral valve. [32] Severe mitral stenosis is defined as a mitral valve area <1.5 cm 2. [8] Progressive mitral stenosis has a normal valve area but will have increased flow velocity across the mitral valve. [8]

  5. Lutembacher's syndrome - Wikipedia

    en.wikipedia.org/wiki/Lutembacher's_syndrome

    Mitral Valve calcification late in life: the test will help to determine if the mitral valve or flaps are becoming hardened and losing their floppiness. pulmonary vascular congestion, marked left atrial enlargement: the test will help to determine if there is a sign of MS and small ASD and how severe both are. [9]

  6. Mitral valve replacement - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve_replacement

    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 stenosis) Causes of mitral valve disease include infection, calcification and inherited collagen disease. Current mitral valve replacement approaches include open heart ...

  7. Mitral valve - Wikipedia

    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 ...

    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.

  9. Mitral regurgitation - Wikipedia

    en.wikipedia.org/wiki/Mitral_regurgitation

    Mitral regurgitation, also known as mitral insufficiency or mitral incompetence, is the backward flow of blood from the left ventricle, through the mitral valve, and into the left atrium, when the left ventricle contracts, resulting in a systolic murmur radiating to the left armpit.
