[Retracted] Diagnostic Value of Abdominal B-Ultrasound for Congenital Heart Disease Complicated with Extracardiac Malformation in the Second Trimester of Pregnancy

Table 5

Comparison of the diagnosis of cardiac malformation by different cardiac sections (n, %).

Ultrasonic section	Number of cases	Number of cases with accurate diagnosis	Diagnostic accuracy (%)
4CV	50	31	62
4CV + (AR-SAV)	50	33	66
4CV + VOYV	50	36	72
4CV + 3VV	50	42	84
4CV + 3VVT	50	45	90

4CV: four-chamber cardiac section; AR-SAV: short axis section of aortic root; VOYV: left and right ventricular outflow tract sections; 3VV: three-vessel plane; 3VVT: three-vessel-trachea plane.
