May support targeted first-trimester screening in high-risk pregnancies; leaves open accuracy versus second-trimester echocardiography for routine use.
Does first-trimester transvaginal echocardiography accurately detect fetal congenital heart disease in singleton pregnancies?
First-trimester transvaginal echocardiography can detect many severe cardiac defects but has lower accuracy than second-trimester transabdominal echocardiography, suggesting it should be reserved for high-risk pregnancies.
Gembruch et al. (1993) studied this question.
