  2. Left atrial enlargement - Wikipedia

    en.wikipedia.org/wiki/Left_atrial_enlargement

    Characterizing the size of the left atrium according to its volume is preferred over a single linear dimension since enlargement can be different for different directions. For example, because of the smaller distance in the thoracic cavity between the sternum and spine , compared to the other directions, less room exists for enlargement of the ...

  3. Left atrial volume - Wikipedia

    en.wikipedia.org/wiki/Left_atrial_volume

    The left atrial volume is commonly measured by echocardiography or magnetic resonance tomography.It is calculated from biplane recordings with the equation: = where A4c and A2c denote LA areas in 4- and 2-chamber views respectively, and L corresponds to the shortest long-axis length measured in either views.

  4. Ejection fraction - Wikipedia

    en.wikipedia.org/wiki/Ejection_fraction

    Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...

  5. Mitral stenosis - Wikipedia

    en.wikipedia.org/wiki/Mitral_stenosis

    As the left atrium increases in size, it becomes more prone to develop atrial fibrillation (AF). In individuals with severe mitral stenosis, the left ventricular filling is dependent on the atrial kick. The loss of the atrial kick due to atrial fibrillation (i.e., blood cannot flow into the left ventricle thus accumulating in the left atrium ...

  6. Atrium (heart) - Wikipedia

    en.wikipedia.org/wiki/Atrium_(heart)

    High in the upper part of the left atrium is a muscular ear-shaped pouch – the left atrial appendage (LAA) (lat: auricula atrii sinistra), which has a tubular trabeculated structure. [9] LAA anatomy as seen in a CT scan is characterized as being in one of four groups: chicken wing (48%), cactus (30%), windsock (19%), and cauliflower(3%).

  8. Cardiac output - Wikipedia

    en.wikipedia.org/wiki/Cardiac_output

    Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...
