From Echocardiography in ICU
The apical echographic window is located at the apex of the left ventricle (apical impulse). In a supine ventilated patient, the LV apex can be more medial.
The direction of the probe is toward the right shoulder of the patient, the notch at 2 or 3 o'clock.
Apical views are very useful for
-evaluation of left and right ventricle function
-assessment of mitral, aortic and tricuspid regurgitation or/and stenosis
-(evaluation of left ventricle diastolic funtion and filling pressure)
You will start with getting the apical 4 chamber view. Once you have obtained all informations from apical 4 chamber, you can tilt the probe upwards to visualize the LV outflow tract and the aortic valve which are more anterior, and get the apical 5 chamber view.
When you rotate your probe 90° counterclockwise, the right chambers will disappear from the imaging plane, you will get the 2 chamber view.
