Study on ultrasound diagnosis and pathological anatomy of fetal complex congenital heart disease in the first trimester.

Purpose: To assess the feasibility of using the stereo-microscope to identify the pathological anatomy of the congenital heart diseases in the first trimester.

Methods: Fifteen fetuses of 8-12 weeks aborted due to prevent miscarriage failure and 42 fetuses of 11-14 weeks with congenital heart diseases were included in the study, we dissected their hearts through a stereo-microscope, then compared with the prenatal ultrasonographic diagnosis.

Results: Using stereomicroscopy, the positive view of the heart and the great arteries, the long axis view of the aortic arch, the inflow tract view of the bottom heart, the semilunar valve view of the bottom heart, and the transverse section of the ventricle were showed contented and obtained satisfactory images, but the structure of atrioventricular valve and venous system had a lower rate of display.
