    en.wikipedia.org/wiki/Tricuspid_regurgitation

    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 ...

  3. Valvular heart disease - Wikipedia

    en.wikipedia.org/wiki/Valvular_heart_disease

    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 congenital ...

  4. Right ventricular hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Right_ventricular_hypertrophy

    Right ventricular hypertrophy (RVH) is a condition defined by an abnormal enlargement of the cardiac muscle surrounding the right ventricle. The right ventricle is one of the four chambers of the heart. It is located towards the right lower chamber of the heart and it receives Deoxygenated blood from the right upper chamber (right atrium) and ...

  5. Pulmonary regurgitation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_regurgitation

    Pulmonary regurgitation. Pulmonary (or pulmonic[4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent [5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole. [6] While a small amount of backflow may occur ordinarily, it is usually only shown ...

  6. 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 ...

  7. Heart murmur - Wikipedia

    en.wikipedia.org/wiki/Heart_murmur

    The exact cause of an Austin Flint murmur is unknown. Hypothesis is that the mechanism of murmur is from the severe aortic regurgitation. In severe aortic regurgitation the jet vibrates the anterior mitral valve leaflet. This causes collision with the mitral inflow during diastole. As such, the mitral valve orifice narrows.

  8. Systolic heart murmur - Wikipedia

    en.wikipedia.org/wiki/Systolic_heart_murmur

    Systolic heart murmur. Auscultogram from normal and abnormal heart sounds. Systolic heart murmurs are heart murmurs heard during systole, [1][2][3] i.e. they begin and end between S1 and S2. Many involve stenosis of the semilunar valves or regurgitation of the atrioventricular valves.

  9. Mitral valve prolapse - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve_prolapse

    Mitral valve prolapse is frequently associated with mild mitral regurgitation, [15] where blood aberrantly flows from the left ventricle into the left atrium during systole. In the United States , MVP is the most common cause of severe, non-ischemic mitral regurgitation. [ 4 ]
