Abstract
OBJECTIVE: To investigate the clinical value of color Doppler echocardiography for the diagnosis of fetal congenital heart disease (CHD). METHODS: 368 cases of high risk fetuses of CHD, aged from 20-40 gestational weeks, were examined by color Doppler echocardiography with Acuson 128 x P/10 color Doppler flow imaging system. The prenatal echocardiographic diagnosis were confirmed by fetal autopsy and echocardiographic examine after birth as well as follow-up. RESULTS: 11 cases of fetal CHD were detected by prenatal echocardiography, of those, 5 cases of CHD were confirmed by fetal autopsy after induction of labor and 5 cases of CHD were confirmed by color Doppler echocardiography after birth, 1 case of false-positive and 1 case of false-negative. CONCLUSIONS: The study suggests that four-chamber view is an important view for detecting fetal CHD by echocardiography, but multiple views are necessary for diagnosis of fetal complex CHD. Color Doppler echocardiography lists as the first choice for prenatal diagnosis of fetal CHD.
