Table 2 Comparison of the advantages and disadvantage of 2DE, traditional 3DE, TrueVue, and TrueVue Glass

From: Rare double orifice mitral valve malformation associated with bicuspid aortic valve in Turner syndrome: diagnosed by a series of novel three-dimensional echocardiography and literature review

  2DE Traditional 3DE TrueVue TrueVue Glass
Advantages Provide sectional morphology images Display 3D geometry of structures Advantages of traditional 3DE Shield the myocardial tissue
  High resolution Show spatial position of MV apparatus Higher resolution Depict edges of orifices
   Delineate anomalous attachments of the sub-valvular apparatus Realistic light and shadow effects Show overall aortic valve, arch and coronary artery in its entity
    Simulate the pathological texture of valves and myocardium Simulate the thin and translucent leaflets
     Show global 3D hemodynamic characteristics
Disadvantages Cannot see the spatial structure characteristics The texture of the lesion quite different from the real pathological specimen Shows that thin valves and chordae may appear false echo loss The scraggly fine texture on the surface of the anatomical structure is insufficient to display
  Multiple ultrasound views are needed to clarify the anatomy of each component of the Mitral valve apparatus The level of structure is unclear Cannot see the surrounding anatomy through the valve  
  The lesion is not intuitive, the diagnosis depends more on the experience of the imaging doctor The boundary is not clear enough   
  Time-consuming and laborious
