Prenatal Detection of Cardiac Anomalies in Fetuses with Single Umbilical Artery: Diagnostic Accuracy Comparison of Maternal-Fetal-Medicine and Pediatric Cardiologist

Table 1

Follow-up rates once MFM performed fetal ultrasound study have diagnosed SUA and fetal echocardiogram performed by pediatric cardiologist.

Group	MFM antenatal study	Follow-up pediatric fetal cardiac study	Follow-up rate (%)	95% confidence interval
A	253	114	45.0	38.9, 51.4
B	12	11	91.7	59.8, 99.6
C	45	24	53.3	38.0, 68.1
D	66	33	50.0	37.5, 62.4
Total	376	182	48.4	43.3, 53.6

Chi-square = 10.6; 𝑃=0.014; Group A: fetuses with isolated SUA; Group B: fetuses with SUA and congenital cardiac anomaly only; Group C: fetuses with SUA and multiple congenital anomalies without cardiac anomaly; Group D: fetuses with SUA and multiple congenital malformations including cardiac anomaly.
