    en.wikipedia.org/wiki/Valvular_heart_disease

    See media help. Valvular heart disease is any cardiovascular disease process involving one or more of the four valves of the heart (the aortic and mitral valves on the left side of heart and the pulmonic and tricuspid valves on the right side of heart). These conditions occur largely as a consequence of aging, [1] but may also be the result of ...

    en.wikipedia.org/wiki/Mitral_valve

    The mitral valve (/ ˈmaɪtrəl /), also known as the bicuspid valve or left atrioventricular valve, is one of the four heart valves. It has two cusps or flaps and lies between the left atrium and the left ventricle of the heart. The heart valves are all one-way valves allowing blood flow in just one direction. The mitral valve and the ...

    en.wikipedia.org/wiki/Mitral_regurgitation

    Definition. 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. [5][3]

    On the left are two standard 2D views (taken from the 3D dataset) showing tricuspid and mitral valves (above) and aortal valve (below). The atrioventricular valves are the mitral valve, and the tricuspid valve, which are situated between the atria and the ventricles, and prevent backflow from the ventricles into the atria during systole.

  6. Tricuspid regurgitation - Wikipedia

    en.wikipedia.org/wiki/Tricuspid_regurgitation

    Tricuspid regurgitation (TR), also called tricuspid insufficiency, is a type of valvular heart disease in which the tricuspid valve of the heart, located between the right atrium and right ventricle, does not close completely when the right ventricle contracts (systole). TR allows the blood to flow backwards from the right ventricle to the ...

  7. Mitral valve prolapse - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve_prolapse

    Mitral valve prolapse (MVP) is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. [4] It is the primary form of myxomatous degeneration of the valve. There are various types of MVP, broadly classified as classic and nonclassic.
