Abstract

OBJECTIVES:

We hypothesized that increased facility with fetal echocardiographic diagnosis by obstetricians is associated with changes in its indications and yields.

METHODS:

We reviewed 300 fetal echocardiograms (December 2002-August 2003) and compared our findings with previous studies.

RESULTS:

Mean maternal age was 31 +/- 6 (range 16-44) years. Gestational age was 24 +/- 5 weeks (mean +/- SD; median 22, range 15-38). Indications for fetal echocardiography included family history of congenital heart disease (CHD) (23%), maternal diabetes (18%), obstetrical scan suspicious for CHD (13%), arrhythmia (12%) maternal rheumatologic disease (7%), extracardiac congenital anomalies (6%), chromosomal anomaly (6%) and exposure to a potential fetal teratogen (5%). High yield indications included chromosomal anomaly (47%) and a suspicious obstetrical scan (42%). Low yield indications included family history of CHD (4%) and teratogen exposure (0%). 1/7 of the patients with increased nuchal translucency had pulmonary atresia/intact ventricular septum. No anomalies were associated with the single umbilical artery.

CONCLUSION:

Indications and yields of fetal echocardiography have changed over the last decade. The frequency of an obstetrical scan suspicious for CHD has increased 2.5 to 3 times over a decade and continues to have high yield. Thus, increasing prenatal detection of CHD depends, to a large extent, on increasing the skills of obstetricians.
