Fig. 2From: Prenatal diagnosis and mRNA profiles of fetal tetralogy of FallotAutopsy findings of fetuses with TOF. A The anterior surface view of the fetal heart showed that the PA was significantly smaller than the aorta. Interestingly, the ductus arteriosus connected the PA and the right common carotid artery. B Then, the RV and RVOT opened, and a muscular obstruction of the RVOT and a small PA were clearly identified. C A perimembranous VSD was observed from the RV, and the root of the aorta overrode the ventricle septum. D The LV was opened, and the perimembranous VSD and the overriding of the aorta were confirmedBack to article page
