Fetal long axis left ventricular outflow tract (LVOT) view:

  • View of the LVOT is obtained via anterior angulation from the starting position of the 4 chamber apical view
  • Aorta arises normally from the posterior morphologic left ventricle
  • Unobstructed LVOT
  • Thin and mobile aortic valve leaflets
  • Normally sized ascending aorta
  • Normal biventricular systolic function
  • Pulsatile aorta anterior and left of the spine

The following are fetal echo examples of long axis LVOT clips.
