Key result
Adding color Doppler to routine second-trimester sonography in low-risk pregnancies detected suspected congenital heart disease in 1% of cases, with 24% of these relying solely on color Doppler.
Why the study?
Does the addition of color Doppler to routine obstetric sonographic surveys improve the detection of congenital heart disease in low-risk fetuses?
Population
1,766 routine fetal anatomic surveys in low-risk patients performed between 16 and 22 weeks gestation
Comparison
Addition of color Doppler to standard grey scale… vs Standard grey scale evaluation alone

Should not yet alter low-risk fetal screening protocols; leaves open whether color Doppler improves outcomes in prospective validation.

Does the addition of color Doppler to routine obstetric sonographic surveys improve the detection of congenital heart disease in low-risk fetuses?
Adding color Doppler to routine second-trimester fetal anatomic surveys in low-risk patients aids in detecting critical pulmonic stenosis that may be missed by grey scale alone.
Allan Nadel (2010) conducted an observational in Congenital heart disease (n=1,766). Color Doppler added to standard grey scale evaluation vs. Standard grey scale evaluation was evaluated on Suspected congenital heart disease. Adding color Doppler to routine second-trimester sonography in low-risk pregnancies detected suspected congenital heart disease in 1% of cases, with 24% of these relying solely on color Doppler.
