    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 ...

    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]

    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 ...

  6. Systolic heart murmur - Wikipedia

    en.wikipedia.org/wiki/Systolic_heart_murmur

    Causes include mitral valve prolapse, tricuspid valve prolapse and papillary muscle dysfunction. Holosystolic (pansystolic) murmurs start at S1 and extend up to S2. They are usually due to regurgitation in cases such as mitral regurgitation, tricuspid regurgitation, or ventricular septal defect (VSD). [4]

  7. Mitral stenosis - Wikipedia

    en.wikipedia.org/wiki/Mitral_stenosis

    Mitral stenosis is a valvular heart disease characterized by the narrowing of the opening of the mitral valve of the heart. [ 1 ] It is almost always caused by rheumatic valvular heart disease. Normally, the mitral valve is about 5 cm 2 during diastole. Any decrease in area below 2 cm 2 causes mitral stenosis.
