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

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

	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
