From the Research

Echocardiography Chambers

The apical 5-chamber view on echocardiography typically includes the following chambers:

  • Left ventricle
  • Left atrium
  • Right ventricle
  • Right atrium
  • Aortic root 1, 2

Chamber Visualization

The apical view provides superior visualization of all four heart chambers compared to parasternal and subcostal views 3 The modified apical 5-chamber view can be used to visualize the left atrium and its compression by ascending and descending aortic aneurysms 2

Measurement Standardization

Standardized intracardiac measurements of two-dimensional echocardiography can be obtained using multiple views, including the apical four-chamber view 4 The use of apical long-axis instead of two-chamber view can give more accurate biplane echocardiographic measurements of left ventricular ejection fraction 5
