Annex 1: Quality criteria of the Left Ventricular Outflow Tract assessment
  1. A Left ventricular cavity (whether anatomically on the left or right) and identification to the tip of the ventricle and interventricular septum.
  2. The presence of a valvular ring and the origin of the overlying vessel, whether or not this ventricle gives rise to a vessel.
  3. An anechogenic Space Above And In The Middle Of The Semilunar Valves (Visualisation And position above the semilunar valves), corresponding to the anterosuperior part of the ventricular cavity on the right.
  4. An anechogenic space located below the semilunar valves (visualisation and position below the semilunar valves), corresponding to the atrium located on the left and behind the left atrioventricular valve.
  5. The relationship between the left atrioventricular valve and the overlying vessel: continuity or discontinuity between the atrioventricular valve and the overlying vessel.
  6. The relationship between the interventricular septum and the overlying vessel: continuity or discontinuity between the septum and the overlying vessel.
  7. Visualisation of the semilunar valves: normal or dysplastic in appearance.
8: Thoracic aorta belongs not to the quality criteria
