Table 2

Comparison of fetuses with cardiac anomaly found by MFM physician versus pediatric cardiologist for Groups A through D (𝑛=182).

	Positive cardiac study FindingsMFM physicians	Positive cardiac study FindingsPediatric cardiologists	Agreement %	95% Confidence interval
Group A 𝑁=114	0	2	98.2% (112/114)	93.2, 99.7

∗Note: 2 cases of cardiac anomalies were missed by both imaging services and were only diagnosed following delivery. 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.
