  2. Marfan syndrome - Wikipedia

    en.wikipedia.org/wiki/Marfan_syndrome

    The most serious complications involve the heart and aorta, with an increased risk of mitral valve prolapse and aortic aneurysm. [1] [8] The lungs, eyes, bones, and the covering of the spinal cord are also commonly affected. [1] The severity of the symptoms is variable. [1]

  3. Mitral regurgitation - Wikipedia

    en.wikipedia.org/wiki/Mitral_regurgitation

    Dysfunction of any of these portions of the mitral valve apparatus can cause regurgitation. [citation needed] The most common cause of MR in developed countries is mitral valve prolapse. [10] It is the most common cause of primary mitral regurgitation in the United States, causing about 50% of cases. Myxomatous degeneration of the mitral valve ...

  4. Mitral valve prolapse - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve_prolapse

    Prior to the strict criteria for the diagnosis of mitral valve prolapse, as described above, the incidence of mitral valve prolapse in the general population varied greatly. [29] Some studies estimated the incidence of mitral valve prolapse at 5 to 15 percent or even higher. [67] One 1985 study suggested MVP in up to 35% of healthy teenagers. [68]

  5. MASS syndrome - Wikipedia

    en.wikipedia.org/wiki/MASS_syndrome

    Other possible symptoms are mitral valve prolapse, a large aortic root diameter, and myopia. [2] The skeletal features found in MASS syndrome include curvature of the spine , chest wall deformities, and joint hypermobility. [2] MASS syndrome and Marfan syndrome are overlapping connective tissue disorders. Both can be caused by mutations in the ...

  6. Valvular heart disease - Wikipedia

    en.wikipedia.org/wiki/Valvular_heart_disease

    Aortic and/or mitral valve disease resulting in severe pulmonary hypertension (pulmonary pressure greater than 75% of systemic pressures) Aortic and/or mitral valve disease with severe LV dysfunction (EF less than 0.40) Mechanical prosthetic valve requiring anticoagulation; Marfan syndrome with or without aortic regurgitation [42]

  7. Wikipedia:Osmosis/Mitral valve diseases - Wikipedia

    en.wikipedia.org/.../Mitral_valve_diseases

    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.

  8. Systolic heart murmur - Wikipedia

    en.wikipedia.org/wiki/Systolic_heart_murmur

    Mitral valve prolapse: This is the most common cause of late systolic murmurs. It can be heard best over the apex of the heart, usually preceded by clicks. The most common cause of mitral valve prolapse is "floppy" valve (Barlow's) syndrome. If the prolapse becomes severe enough, mitral regurgitation may occur.

  9. Bentall procedure - Wikipedia

    en.wikipedia.org/wiki/Bentall_procedure

    The Bentall procedure is a type of cardiac surgery involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined disease of the aortic valve and ascending aorta, including lesions associated with Marfan syndrome.
