Color Doppler Fetal Intelligent Navigation Echocardiography (color Doppler information only): success rates of obtaining nine fetal echocardiography views with appropriate color Doppler information after applying intelligent navigation to 27 normal spatiotemporal image correlation (STIC) volume datasets using a combination of diagnostic planes and/or Virtual Intelligent Sonographer Assistance (VIS‐Assistance)

Fetal echocardiography view	Diagnostic plane and/or VIS‐Assistance (n = 27)
	n (%)	95% CI (%)
1. Four chamber	27 (100)	85–100
2. Five chamber	24 (89)	71–97
3. LVOT	26 (96)	80– > 99.9
4. Short‐axis view of great vessels/RVOT	27 (100)	85–100
5. 3VT*	27 (100)	85–100
6. Abdomen/stomach†	27 (100)	85–100
7. Ductal arch‡	27 (100)	85–100
8. Aortic arch§	27 (100)	85–100
9. SVC and IVC	9 (33)	19–52
SVC	23 (85)	67–95
IVC	9 (33)	19–52

Wald method used to calculate two‐sided CIs for proportions; as true proportion cannot exceed 100%, upper CIs were truncated at 100%.

^*No flow in superior vena cava (SVC) in 74% (n = 20) and flow in SVC in 26% (n = 7).

^†No flow in both inferior vena cava (IVC) and descending aorta in 70% (n = 19), no flow in descending aorta, but flow in IVC in 22% (n = 6), flow in both IVC and descending aorta in 4% (n = 1) and flow in descending aorta, but no flow in IVC in 4%; n = 1.

^‡Flow in descending aorta in 59% (n = 16) and no flow in descending aorta in 41% (n = 11).

^§Flow in descending aorta in 56% (n = 15) and no flow in descending aorta in 44% (n = 12).

3VT, three vessels and trachea; LVOT, left ventricular outflow tract; RVOT, right ventricular outflow tract.
