  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 ...

  3. Aortic valve area calculation - Wikipedia

    en.wikipedia.org/wiki/Aortic_valve_area_calculation

    Planimetry is the tracing out of the opening of the aortic valve in a still image obtained during echocardiographic acquisition during ventricular systole, when the valve is supposed to be open. While this method directly measures the valve area, the image may be difficult to obtain due to artifacts during echocardiography, and the measurements ...

  4. Transthoracic echocardiogram - Wikipedia

    en.wikipedia.org/wiki/Transthoracic_echocardiogram

    In this view, the mitral valve and aortic valve are in view and is roughly similar to the parasternal long axis. In this view, the LV outflow tract is best in alignment with the probe and so gives the best estimate of flow through the LVOT, which is commonly used to estimate aortic stenosis. Structures: Aortic valve; Mitral valve; Left ventricle

  5. 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. Early diagnosis of mitral stenosis ...

  6. Pressure–volume loop analysis in cardiology - Wikipedia

    en.wikipedia.org/wiki/Pressure–volume_loop...

    This is a narrowing of the mitral valve orifice when the valve is open. Mitral stenosis impairs LV filling so that there is a decrease in end-diastolic volume (preload). This leads to a decrease in stroke volume by the Frank–Starling mechanism and a fall in cardiac output and aortic pressure.

  7. Cardiac physiology - Wikipedia

    en.wikipedia.org/wiki/Cardiac_physiology

    Cardiac physiology or heart function is the study of healthy, unimpaired function of the heart: involving blood flow; myocardium structure; the electrical conduction system of the heart; the cardiac cycle and cardiac output and how these interact and depend on one another.

  8. Mitral regurgitation - Wikipedia

    en.wikipedia.org/wiki/Mitral_regurgitation

    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.

  9. Mitral valve prolapse - Wikipedia

    en.wikipedia.org/wiki/Mitral_valve_prolapse

    Mitral valve prolapse classification. Diagnosis of mitral valve prolapse is based on modern echocardiographic techniques which can pinpoint abnormal leaflet thickening and other related pathology. Echocardiography is the most useful method of diagnosing a prolapsed mitral valve. Two- and three-dimensional echocardiography is particularly ...
