선천성 심장질환의 진단에서 태아 심초음파 검사의 진단적 유용성

Abstract

It is important to recognize congenital heart disease (CHD) prenatally, because CHD is the most common congenital major anomaly in neonates that contributes to significant perinatal morbidity and mortality. Previous studies have demonstrated the usefulness of the four-chamber view (4-CV) for the prenatal detection of cardiac anomalies. Our purpose was to determine whether the addition of long axis view (LAV) and short axis view (SAV) would detect more congenital cardiac anomalies. This study included 5,598 pregnant women who were obtained all 4-CV, LAV and SAV, and delivered in Severance hospital from Jan 1991 through Dec 1996. The diagnostic accuracy of each view was evaluated. Information of outcome was obtained from physical examinations, postnatal echocardiography and/or autopsies. The 4-CV detected 28 (51.9%) of the 54 fetuses with abnormal heart. Adding the LAV increased the sensitivity to 64.8% and adding the SAV increased the sensitivity to 57.4%. Adding the LAV and SAV increased the sensitivity to 64.8% and was same as adding only LAV. In conclusion, adding the only LAV to the standard 4-CV will result in the more prenatal detection of cardiac anomalies.
