  2. 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 .

  3. Regurgitation (circulation) - Wikipedia

    en.wikipedia.org/wiki/Regurgitation_(circulation)

    In The Framingham Heart Study presence of any severity of tricuspid regurgitation, ranging from trace to above moderate was in 82% of men and in 85.7% of women. [2] Mild tricuspid regurgitation tend to be common and benign and in structurally normal tricuspid valve apparatus can be considered a normal variant. [1]

  4. Tricuspid valve - Wikipedia

    en.wikipedia.org/wiki/Tricuspid_valve

    The tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...

  5. Koch's triangle - Wikipedia

    en.wikipedia.org/wiki/Koch's_triangle

    It is an anatomical area located at the base of the right atrium, and its boundaries are the coronary sinus orifice, tendon of Todaro, and the septal leaflet of the right atrioventricular valve (also known as the tricuspid valve). [2] It is anatomically significant because the atrioventricular node is located at the apex of the triangle. The ...

  6. Mitral valve prolapse - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve_prolapse

    It is composed of two leaflets, one anterior and one posterior, that close when the left ventricle contracts. [35] Each leaflet is composed of three layers of tissue: the atrialis, fibrosa, and spongiosa. Patients with classic mitral valve prolapse have excess connective tissue that thickens the spongiosa and separates collagen bundles in the ...

  7. Tricuspid valve stenosis - Wikipedia

    en.wikipedia.org/wiki/Tricuspid_valve_stenosis

    Tricuspid valve stenosis itself usually does not require treatment. If stenosis is mild, monitoring the condition closely suffices. However, severe stenosis, or damage to other valves in the heart, may require surgical repair or replacement. The treatment is usually by surgery (tricuspid valve replacement) or percutaneous balloon valvuloplasty ...

  8. Right ventricular hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Right_ventricular_hypertrophy

    Tricuspid regurgitation is typically treated conservatively by aiming to treat the underlying cause and following up the patient regularly. [12] Surgery is considered in more serious situations where the patient is severely symptomatic. Surgical options include either: replacement of the valve or repair of the valve (termed annuloplasty). [3]

  9. Papillary muscle - Wikipedia

    en.wikipedia.org/wiki/Papillary_muscle

    The papillary muscles are muscles located in the ventricles of the heart. They attach to the cusps of the atrioventricular valves (also known as the mitral and tricuspid valves) via the chordae tendineae and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction).
