  2. Mitral valve - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve

    The mitral valve is typically 4 to 6 square centimetres (0.62 to 0.93 sq in) in area and sits in the left heart between the left atrium and the left ventricle. [5] It has two cusps: an anterior one, and a posterior one. [6] The opening of the mitral valve is surrounded by a fibrous ring known as the mitral annulus. The anterior cusp attaches to ...

    The mitral valve is also called the bicuspid valve because it contains two leaflets or cusps. The mitral valve gets its name from the resemblance to a bishop 's mitre (a type of hat). It is on the left side of the heart and allows the blood to flow from the left atrium into the left ventricle .

    An aortic homograft is an aortic valve from a human donor, retrieved either after their death or from a heart that is removed to be replaced during a heart transplant. [12] A pulmonary autograft, also known as the Ross procedure , is where the aortic valve is removed and replaced with the patient's own pulmonary valve (the valve between the ...

    en.wikipedia.org/wiki/Aortic_valve

    Aortic valve repair or aortic valve reconstruction describes the reconstruction of both form and function of the native and dysfunctioning aortic valve. Most frequently it is applied for the treatment of aortic regurgitation. It can also become necessary for the treatment of aortic aneurysm, or less frequently for congenital aortic stenosis. [8]

  6. Aortic valve replacement - Wikipedia

    en.wikipedia.org/wiki/Aortic_valve_replacement

    The posterior leaflet is in continuation with the anterior leaflet of the mitral valve (the tissue is called the aorto-mitral curtain). [4] The aortic valve is opened during systole, the driving force for it to open is the difference in pressure between the contracting left ventricle of the heart and the aorta.

  7. Cardiac cycle - Wikipedia

    en.wikipedia.org/wiki/Cardiac_cycle

    The section shows: 1) the opened ventricles contracting once per heartbeat—that is, once per each cardiac cycle; 2) the (partly obscured) mitral valve of the left heart; 3) the tricuspid and pulmonary valves of the right heart—note these paired valves open and close oppositely. + (The aortic valve of the left heart is located below the ...
