TTE views to assess the aortic valve
From Echocardiography in ICUParasternal long axis view. In this view you will see the cross section of the aortic valve across the right and non-coronary cusp. You can visualize and measure the sinus of Valsalva and the aortic root. You can see the left ventricle outflow tract and look for sub-aortic stenosis.
Parasternal short axis view, level of the aortic valve. On this view you can see the cross section of the aortic valve and the three cusps. This is the best view to look for bicuspid aortic valve. On this picture, you can see a bicuspid aortic valve.
Apical 5 chamber view. This view is obtained by tilting anteriorly the probe from the apical 4 chamber view. You can see the left ventricle outflow tract, the aortic valve and the aortic root. This is a good view to assess the extent of aortic regurgitation. In this view you usually obtain good alignement of the doppler beam with the LV outflow tract for the quantitation of aortic stenosis.
Apical 3 chamber view. This view is obtained by rotating the probe counter-clockwise from apical 2 chamber view. You get the same informations about the aortic valve than from apical 5 chamber view.
