    en.wikipedia.org/wiki/Tricuspid_regurgitation

    During open heart surgery for another issue (e.g. mitral valve), fixing the tricuspid valve may be considered, but medical consensus is unclear. Some argue that even mild to moderate tricuspid regurgitation should be addressed, while others take a more conservative approach. Infective endocarditis or traumatic lesions are other indications. [14]

    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.

    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]

  6. Mitral valve - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve

    The mitral valve and the tricuspid valve are known as the atrioventricular valves because they lie between the atria and the ventricles. [1] In normal conditions, blood flows through an open mitral valve during diastole with contraction of the left atrium, and the mitral valve closes during systole with contraction of the left ventricle. The ...

  7. Chordae tendineae - Wikipedia

    en.wikipedia.org/wiki/Chordae_tendineae

    Parachute mitral valve occurs when all the chordae tendineae of the mitral valve attach to a single papillary muscle. [9] [10] [11] This causes mitral valve stenosis at an early age. [10] It is a rare congenital heart defect. [11] Although it often causes mitral insufficiency, it may not present any symptoms. [10]
