Fig. 5From: Prenatal evaluation of fetal atrioventricular valves by real-time 4D volume imaging with electronic matrix probeThe 4D surface rendered image of atrioventricular valves obtained from reconstruction of RT 4D volume imaging in a fetus with complete atrioventricular septal defect. The 4D image can clearly show the common atrioventricular valves with five leaflets as a group of petal-like structures (indicated by arrows) during diastole. LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricleBack to article page
